The wave function [in S.I unit] for an electromagnetic wave is given as

\psi \left( {x,t} \right) = {10^3}\sin \pi \left[ {3 \times {{10}^6}x - 9 \times {{10}^{14}}t} \right]

The speed of the wave is [in m/s]

View answer and explanation

Correct option: B

3 \times {10^8}

Option B (

3 \times {10^8}

) is correct because the speed of the wave can be found by dividing the coefficient of t by the coefficient of x.
