Colour and frequency; differential effects in transmission, absorption and diffuse reflection — WJEC GCSE Physics
In summary: Colour and frequency; differential effects in transmission, absorption and diffuse reflection is a key topic in WJEC GCSE Physics. Key exam tip: Ensure you can explain why an object appears a certain colour when illuminated by non-white light (e.g., a red object under blue light)
Exam Tips for Colour and frequency; differential effects in transmission, absorption and diffuse reflection
- Ensure you can explain why an object appears a certain colour when illuminated by non-white light (e.g., a red object under blue light)
- Be prepared to describe how colour filters work by transmitting specific wavelengths and absorbing others
Marking Points
- Explanation of how colour is related to differential absorption, transmission, specular reflection, and scattering
- Application of knowledge to explain changes in the appearance of coloured objects under different coloured lights
- Application of knowledge to explain changes in the appearance of coloured objects when viewed through colour filters
