A plane electromagnetic wave of frequency 500 MHz is travelling in vacuum along y – direction. At a particular point in space and time, B→=8.0×10−8z^T. The value of electric field at this point is: (Speed of light =3×108ms−1 ) x^, y^, z^ are unit vectors along x, y and z directions.

C=EBE = CB =24 v/mDirection of (E¯×B¯) is direction of wave.

A plane electromagnetic wave of frequency 500 MHz is travelling in vacuum along y – direction. At a particular point in space and time, $\vec{B} = 8.0 \times 10^{- 8} \hat{z} T .$ The value of electric field at this point is: (Speed of light $= 3 \times 10^{8} m s^{- 1}$ ) $\hat{x}, \hat{y}, \hat{z}$ are unit vectors along x, y and z directions.
