Assertion (A) : Radio waves bend in a magnetic field.
Reason (R) : Radio waves are electromagnetic in nature.
A
Both A and R are individually true and R is the correct explanation of A
B
Both A and R are individually true but R is not the correct explanation of A
C
A is true but R is false
D
A is false but R is true
Correct Answer: Option D
Explanation
1. Assertion (A): Radio waves are electromagnetic waves and, like other electromagnetic waves (e.g., light), they travel in straight lines unless refracted, diffracted, or reflected. They are composed of oscillating electric and magnetic fields but carry no net electric charge. A static magnetic field does not exert a force on or bend uncharged waves. Assertion (A) is false.
2. Reason (R): Radio waves are indeed electromagnetic in nature, consisting of propagating electric and magnetic fields. Reason (R) is true.
