The wave function (in S.I units) 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 wave is :

View answer and explanation

Correct option: B

3 \times {10^8}\,m/s

Option B (

3 \times {10^8}\,m/s

) is correct because the speed of the wave is calculated by dividing the coefficient of time by the coefficient of position in the wave equation.
