| Assertion (A): Gamma rays are electromagnetic waves having the smallest wavelength. |
| Reason (R): Gamma rays are having the lowest frequency. |
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) A is false and R is true
Correct Answer: C
Solution :
Option [c] is correct. Explanation: Gamma rays are electromagnetic waves having the smallest wavelength. So, the assertion is true. Relation between wavelength and frequency is \[\operatorname{v}=c/\lambda \]. c is the velocity of light and same for all electromagnetic waves. For Gamma rays wavelength being smallest, frequency will be highest. So, the reason is false.
