The expression of magnetic field in a plane electromagnetic wave is given by
` vecB = 2.5 xx 10^(-7) sin ( 600 x + 2 xx 10^(11) t ) hatj T `
(a) Calculate the wavelength and frequency of the wave .
Calculate ampletude for the electric field .

Explanation

To solve the problem step by step, we will break down the calculations for the wavelength, frequency, and amplitude of the electric field from the given expression of the magnetic field in a plane electromagnetic wave.

### Given:
The magnetic field \( \vec{B} \) is given by:
\[ \vec{B} = 2.5 \times 10^{-7} \sin(600x + 2 \times 10^{11}t) \hat{j} \, \text{T} \]
