| T |
The maximum displacement is called the amplitude. |
|
What is the maximum displacement of a wave called? |
|
|
| T |
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). |
|
How is the wavelength of a wave measured? Starter: draw and label a transverse wave (recall from previous topic) |
|
|
| T |
Waves transfer energy from one place to another, but generally not matter (particles). |
|
What do waves usually transfer? |
|
|
|
Water waves and light waves are transverse waves, because the displacement is perpendicular to the direction of the wave. |
|
Why are water waves and light waves described as 'transverse'? Use string to model the movement of transverse waves (link back to sound waves being transverse) |
|
|
|
When light (or waves) waves change speed they change direction. This is called refraction. |
|
What is refraction? Refraction light |
|
|
|
Light waves can travel through a vacuum. |
|
Why can light travel through a vacuum? |
|
|
|
Light is called electromagnetic radiation. |
|
What is another name for light? |
|
|
|
When all colours of light mix they add up to form white light. |
|
What happens when all the colours of light mix? Splitting white light class set |
|
|
| W |
The different colours of light are refracted (bend) different amounts.
Red is refracted the least, Violet is refracted the most. |
|
Why are the colours of white light separated in a rainbow? |
|
|
| T |
The different colours have different frequencies of light. |
|
Why do different colours of light bend different amounts? |
|
|
| T |
The higher the frequency of light, the more it is refracted by the prism. |
|
How does the frequency of light affect how much is it bent by a prism? |
|
|
|
Light waves do not involve particles, they are displacements in electrical and magnetic fields. |
|
How do light waves travel if not by particles? Bell in Bell jar and vacuum pump
focus on object in the jar as still being able to be seen by the light |
|
|
| W |
The higher the frequency the higher the energy of the wave. |
|
How does frequency affect the energy of a wave? Create a wave in a rope or rubber tubing. Which takes more energy to create, a rapidly changing wave (high frequency) or a slowly changing wave |
|
|
| W |
Red has the lowest frequency (of visible light).
Violet has the highest frequency (of visible light) |
|
How do the frequencies of red visible light and violet visible light compare? |
|
|
|
The speed of light through a vacuum is always 3x10^8 m/s |
|
What is the speed of light in a vacuum? |
|
|
| W |
Red has the lowest energy (of visible light).
Violet has the highest energy (of visible light) |
|
How do the energies of red visible light and violet visible light compare? |
|

When colours of paint are mix they subtract, forming brown. |
|
What happens when colours of paint are mixed? https://phet.colorado.edu/sims/html/color-vision/latest/color-vision_en.html |
