JEE MainPhysicsElectromagnetic WavesMCQ+4 / −1
A plane electromagnetic wave of frequency 25 GHz is propagating in vacuum along the z-direction. At a particular point in space and time, the magnetic field is given by B→=5×10−8j^T\overrightarrow B = 5 \times {10^{ - 8}}\widehat jTB=5×10−8j​T. The corresponding electric field E→\overrightarrow EE is (speed of light c = 3 × 108 ms–1)
