Colour filters - WORKED EXAMPLE - GCSE Physics

Показать описание

This video is a worked example on reflection, more specifically the reflection of colour. Objects of colour appear different under different coloured filters. A coloured filter will only transmit light that's the same colour and absorb every other colour. Therefore colours viewed through a filter of a different colour will appear black and any white will appear the same colour as the filter.

The question is as follows:
The flag of The Gambia is shown.
a) Sketch what you would observe if viewed through a red filter.
b) Sketch what you would observe if viewed through a blue filter.

Thanks for watching,
