Mastery Evidence
- Lists the colours of the visible spectrum in order of increasing frequency
- Explains why a prism disperses white light into a spectrum
- Explains why a red object looks red under white light but black under blue light
- Predicts the colour of an object seen through a colour filter
Assessment Prompt
If your child shone white light through a prism, could they explain why a rainbow of colours appears — and then predict what colour a blue jumper would look under red light and why?
