- (i) and (iv) only
- (ii) and (iii) only
- (i), (ii) and (iv) only
- (i), (ii) and (iii) only
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Analyze statement (i).
Accelerating charges produce changing electric and magnetic fields which generate electromagnetic waves.
Hence statement (i) is correct.
Step 2: Analyze statement (ii). Electromagnetic waves transport energy and momentum but not electric charge. Hence statement (ii) is correct.
Step 3: Analyze statement (iii). In electromagnetic waves: \[ \text{Energy in electric field}=\text{Energy in magnetic field} \] Hence statement (iii) is correct.
Step 4: Analyze statement (iv). Electromagnetic waves travel with different speeds in different media. Maximum speed occurs in vacuum: \[ c=3\times10^8 m/s \] Hence statement (iv) is incorrect. Therefore correct option is: \[ \boxed{(i),(ii),(iii)\text{ only}} \]
Step 2: Analyze statement (ii). Electromagnetic waves transport energy and momentum but not electric charge. Hence statement (ii) is correct.
Step 3: Analyze statement (iii). In electromagnetic waves: \[ \text{Energy in electric field}=\text{Energy in magnetic field} \] Hence statement (iii) is correct.
Step 4: Analyze statement (iv). Electromagnetic waves travel with different speeds in different media. Maximum speed occurs in vacuum: \[ c=3\times10^8 m/s \] Hence statement (iv) is incorrect. Therefore correct option is: \[ \boxed{(i),(ii),(iii)\text{ only}} \]
