What travels from one place to another in a wave?	Waves transfer energy from one place to another, but not matter.	Waves transfer energy and matter from one place to another.	Waves transfer matter from one place to another, but not energy.	Waves do not transfer anything.	Waves transfer energy from one place to another, but generally not matter (particles).

The distance between like places on a wave, such as peak-to-peak or trough-to-trough, is known as the wavelengths. Wavelength is measured in metres (m).
What type of wave is a water wave?	Transverse wave.	Longitudinal wave.	Mechanical wave.	Electromagnetic wave.	Waves on water as undulations which travel through water with transverse motion as the wave moves horizontally but the water moves up and down.
What is reflection?	A wave bouncing off an object.	A wave spreading out through a gap.	A wave changing direction.	A wave splits into components.	Water waves can be reflected. This is when waves bounce off an object.

What is diffraction?	A wave spreading out through a gap.	A wave changing direction.	A wave bouncing off an object.	A wave splits into components.	Water waves can be diffracted. This is when waves spread out through a gap.
What is wave superposition?	When waves add together creating bigger peaks or smaller peaks.	When waves add together creating bigger peaks.	When waves add together creating smaller peaks.	When waves cancel each other out.	Water waves can add or cancel - superposition: When peaks meet you get bigger peaks. When a peak meets a trough then they cancel out.
How is sound produced?	Sound is produced by the vibrations of objects.	Sound is produced by a stationary object.	Sound is produced by excitation of electrons.	Sound is produced by vibrations in a vacuum.	Sound is produced by vibrations of objects.
What is the frequency of a wave?	The frequency of a wave is number of waves in a bit of time.	The frequency of a wave is how long it takes to complete one wave.	The frequency of a wave is maximum displacement within the wave.	The frequency of a wave is the distance between the trough and peak of a wave.	The number of vibrations (waves) in a bit of time is known as the frequency of a wave.
What unit is frequency measured in?	Frequency is measured in hertz (Hz).	Frequency is measured in meters (m).	Frequency is measured in seconds (s).	Frequency is measured in meters per second (m/s).	Frequency is measured in hertz (Hz) which means number per second.
What is the relationship between frequency and the sound produced?	The higher the frequency of sound, the higher the pitch.	The higher the frequency of sound, the lower the pitch.	The higher the frequency of sound, the higher the volume.	The higher the frequency of sound, the lower the volume.	The higher the frequency of sound, the higher the pitch.
What does a high frequency signal look like on an oscilloscope, compared to a low frequency signal?	The closer the peaks on an oscilloscope the higher the frequency of the signal and therefore the wave.	The further apart the peaks on an oscilloscope the higher the frequency of the signal and therefore the wave.	The taller the peaks on an oscilloscope the higher the frequency of the signal and therefore the wave.	The shorter the peaks on an oscilloscope the higher the frequency of the signal and therefore the wave.	The closer the peaks on an oscilloscope the higher the frequency of the signal and therefore the wave.
What does a high amplitude signal look like on an oscilloscope, compared to a low amplitude signal?	The taller the peaks on an oscilloscope the higher the amplitude of the signal and therefore wave.	The shorter the peaks on an oscilloscope the higher the amplitude of the signal and therefore wave.	The further apart the peaks are on an oscilloscope the higher the amplitude of the signal and therefore wave.	The closer the peaks on an oscilloscope the higher the amplitude of the signal and therefore wave.	The taller the peaks on an oscilloscope the higher the amplitude of the signal and therefore wave.
What is the relationship between energy and amplitude?	The higher the amplitude of the wave, the more energy in the wave and therefore the louder the sound.	The higher the amplitude of the wave, the less energy in the wave and therefore the louder the sound.	The higher the amplitude of the wave, the more energy in the wave and therefore the quieter the sound.	The higher the amplitude of the wave, the less energy in the wave and therefore the quieter the sound.	The higher the amplitude of the wave, the more energy in the wave and therefore the louder the sound.
What is the auditory range of humans?	The auditory range of humans is from 20 Hz to 20 kHz.	The auditory range of humans is from 30 Hz to 30 kHz.	The auditory range of humans is from 30 Hz to 10 kHz.	The auditory range of humans is from 20 Hz to 10 kHz.	The auditory range of humans is from 20 Hz to 20 kHz.
What is ultrasound?	Sound frequencies above the hearing range of humans are called ultrasound.	Sound frequencies below the hearing range of humans are called ultrasound.	Sound frequencies that can only be heard by bats are called ultrasound.	Sound frequencies within the hearing range of humans are called ultrasound.	Sound frequencies above the hearing range of humans are called ultrasound.
What can ultrasound be used for and why?	Ultrasound can be used to pass on energy and therefore be used for cleaning and physiotherapy.	Ultrasound can be used to collect energy and therefore be used for cleaning and physiotherapy.	Ultrasound can be used to collect energy and therefore be used for pregnancy scans.	Ultrasound can be used to pass energy though anything and therefore be used for pregnancy scans.	Ultrasound can be used to pass on energy and therefore be used for cleaning and physiotherapy.
What type of wave is a sound wave?	Sound waves are longitudinal waves.	Sound waves are transverse waves.	Sound waves are mechanical waves.	Sound waves are electromagnetic waves.	Sound waves are longitudinal as the motion of the particles is along the direction the wave is travelling.
Why does sound need a medium to travel?	Sound needs a medium of particles to travel, as the energy in sound waves is passed on by the collision of particles.	Sound needs a medium of particles to travel, as the energy in sound waves is passed on by the rubbing of particles.	Sound needs a medium so that it not too large.	Sound needs a medium so that it is not too small.	Sound needs a medium of particles to travel, as the energy in sound waves is passed on by the collision of particles.
In which of state of matter (solid, liquid, gas) does sound sound travel fastest?	Sound travels fastest in solids.	Sound travels fastest in liquids.	Sound travels fastest in gases.	Sound travels slowest in liquids.	Sound travels fastest in solids and slowest in gasses.
Why does the sound travel faster?	Sound travels fastest in solids as the particles are closest together and so the collisions are passed on faster.	Sound travels fastest in solids as the particles are closest together and so the collisions are passed on slower.	Sound travels fastest in gases as the particles are closest together and so the collisions are passed on faster.	Sound travels fastest in gases as the particles are closest together and so the collisions are passed on slower.	Sound travels fastest in solids as the particles are closest together and so the collisions are passed on faster. Sound travels slowest in gasses as the particles are farthest apart and so the collisions are passed on slower.
What happens when sound waves collide with an object such as an ear drum?	The sound energy is absorbed by the ear drum.	The sound energy is created by the ear drum.

Echoes are the refraction of a sound wave with a long time delay.	Echoes are the refraction of a sound wave with a short time delay.	Echoes are just the reflection of a sound wave with an big enough time delay, such that your brain separates the sound into two distinct events.
What is the equation to calculate speed?	speed = distance / time	speed = distance x time	time = speed / distance	time = distance x speed	Speed = distance / time With reflections / echoes the sound travels twice the distance of the person making the sound and the wall.
