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
