Question 14 of 25intermediate💡 UnderstandShort Answer2 marks

Do the colours of different objects appear to change? How did a blue object look through thin yellow plastic?

Correct Answer

Yes, the colours of different objects appear to change when viewed through coloured transparent materials.

A blue object viewed through thin yellow plastic may appear greenish or dark because yellow and blue are opposite colours. The yellow filter allows yellow light to pass through but blocks or changes the blue light reflected by the object.

This creates a different colour perception than the original blue.

Explanation

Activity 4 on Page 7 encourages students to observe colour mixing effects through coloured transparent materials. When viewing coloured objects through different coloured transparent materials, the colours interact and create new visual perceptions. This demonstrates how transparent materials can filter and modify light.
