Question

Assertion (A): The white light of sun is composed of seven colours. Reason (R): When white light passes through a glass prism it splits the white light into seven colours.

Answer 1

Explanation:

Assertion is true , Reason is true and Reason is the correct explanation of assertion

Answer 2

The correct answer is:

Both A and R are true and R is the correct explanation of A.

This is because the white light of the sun is composed of seven colours, which are red, orange, yellow, green, blue, indigo and violet. These colours have different wavelengths and frequencies, and hence they bend differently when they pass through a glass prism. This phenomenon is called dispersion of light, and it splits the white light into seven colours. Therefore, R is the correct explanation of A.

This is an example of a question that requires logical reasoning and scientific knowledge. The possible answers are:

• Both A and R are true and R is the correct explanation of A.
• Both A and R are true but R is not the correct explanation of A.
• A is true but R is false.
• A is false but R is true.
• Both A and R are false.

The correct answer is:

Both A and R are true and R is the correct explanation of A.
