JEE PYQ: Electromagnetic Waves Question 27
Question 27 - 2019 (08 Apr 2019 Shift 1)
A plane electromagnetic wave travels in free space along the x-direction. The electric field component of the wave at a particular point of space and time is $E = 6$ Vm$^{-1}$ along y-direction. Its corresponding magnetic field component, B would be:
(1) $2 \times 10^{-8}$ T along z-direction
(2) $6 \times 10^{-8}$ T along x-direction
(3) $6 \times 10^{-8}$ T along z-direction
(4) $2 \times 10^{-8}$ T along y-direction
Show Answer
Answer: (1)
Solution
$B_0 = \frac{E_0}{c} = \frac{6}{3 \times 10^{8}} = 2 \times 10^{-8}$ T along z-direction.
