Question

A red flower kept in green light will appear

• A. red
• B. yellow
• C. black
• D. white

Hint:

Colour of an object = colour of light it reflects. If incident light has no component of that colour, object appears black.

Answer 1

The Correct Option is C

Step 1: Concept:
A red flower reflects red light and absorbs other colours. Green light contains no red component.
Step 2: Explanation:
Red flower appears red because it reflects red wavelength. When illuminated with green light, it absorbs green light (no red to reflect). Thus, it appears black (no light reflected).
Step 3: Conclusion:
Thus, the flower appears black.
