AQA GCSE Visible Light(Physics)
Visible Light
White light is made up of seven different colours. This can be shown with the visible light spectrum.
These colours are Red, Orange, Yellow, Green, Blue, Indigo and Violet.
Each colour within the visible light spectrum has its own range of wavelength and frequency.
So red light has a different frequency and wavelength compared to orange light and so on.
From Red light to violet light, as wavelength decreases and frequency increases, this is an inversely proportional relationship
Remembering the colours
Practice Question
1.State the names of the 7 colours that white light is made up of
2.Which colour has a longer wavelength Blue light or Yellow light?
3. Which colour has a higher frequency Blue light or yellow light?
4. What type of relationship occurs between wavelength and frequency?
