| Assertion (A): Microwaves are considered suitable for radar system. |
| Reason (R): Microwaves are of shorter wavelength. |
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: A
Solution :
Option [a] is correct Explanation: Wavelength of microwaves ranges from \[{{10}^{-3}}\] to 0.1 m. Hence, it can be bounced from any small object. Hence, it is suitable for radar system. So, the assertion and reason both are true and the assertion is properly explained
