NEET Physics Properties of EM Waves Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 12

Assertion (A): Gamma rays typically originate from atomic nuclei. | Reason (R): The wavelength of electromagnetic waves is often correlated with the characteristic size of the system that radiates.

A

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

B

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

C

A is true but R is false.

D
