The electric field of an electromagnetic wave in free space is represented at 0 E E = cos ( ω t – kz) i ˆ .The corresponding magnetic induction vector will be:

1. B = E 0 C cos ( ω t + kZ) j ˆ
2. B = E 0 C cos ( ω t – kZ) j ˆ
3. C E B 0 = cos( ω t–kz) j ˆ
4. ( ) j ˆ kz t cos C E B 0 + ω = CAREER POINT CAREER POINT Ltd., CP Tower, IPIA, Road No.1, Kota (Raj.), Ph: 081-47250011 www.careerpoint.ac.in 6 JEE Main Online Paper
