Assertion (A): The speed of light for different colours is same in air.

Reason (R): The speed of light for different colours is the different in glass.

विकल्प

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion.

Explanation:

Both statements are true. Different colours travel at approximately the same speed in air, but at different speeds in glass. The reason does not explain why their speeds are the same in air.
