Assertion: A red object appears dark in the yellow light .
Reason: The red colour is scattered less.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are truw but reason is not correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

B

Explanation

A red object reflects red colour from a light falling on it.Thus when this object is viewed in yellow light then it absorbs all yellow light falling on it and appears dark.From Rayleigh's scattering is invesely proportinal to `gamma^(4)`.Red colour has largest wavelength,therefore this colour is scrattered least as compared to other colours.
