The magnetic field in a electromagnetic wave is given by B y = 2 × 1 0 − 7 sin ( 0.5 + 1 0 3 x + 1.5 × 1 0 11 t ) T The frequency of the wave is (in GHz )

Comparing the given equation with B y = B 0 sin [ 2 π ( λ x + T t ) ] We get, λ = 0.5 × 1 0 3 2 π = 1.26 cm and T 1 = v = 2 π ( 1.5 × 1 0 11 ) = 23.9 GHz

Answer:

Solution:

Comparing the given equation with $B_{y} = B_{0} sin [2 π (\frac{x}{λ} + \frac{t}{T})]$ We get, $λ = \frac{2 π}{0.5 \times 1 0 ^{3}} = 1.26 cm$ and $\frac{1}{T} = v = \frac{( 1.5 \times 1 0 ^{11} )}{2 π} = 23.9 GHz$
