Assertion : `X` - rays travel with the speed of light.
Reason : `X`- rays are electromagnetic rays.

A

If both assertion and reason are true and reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not correct explanation of the assertion.

C

If assertion is true but the reason is false.

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Like light rays , `X` - rays are electromagnetic waves , they show all important properties of light rays . They travel with speed of light they under go reflection , refraction , interference , polarization.
