The electric field in a plane electro magnetic wave is given by $E_z=60\sin (0.5 × 10^3x+1.5 × 10^{11} t) V/m$. What is the wavelength and magnetic field amplitude of the wave? |
$1.26 m, 2 × 10^{-7} T$ $1.26 cm, 2 × 10^{-7} T$ $1.26 m, 9 × 10^{9} T$ $1.26 cm, 9 × 10^{9} T$ |
$1.26 cm, 2 × 10^{-7} T$ |
The correct answer is Option (2) - $1.26 cm, 2 × 10^{-7} T$ |
