A sinusoidal electromagnetic wave is propagating in vacuum. At a given point and at a particular time the electric field is in the x direction and the magnetic field is in the -y direction. What is the direction of propagation of the wave

Explanation:

A wave is a disturbance or oscillation that passes through spatial time and is followed by a transfer of energy. For transverse waves, the propagation direction is perpendicular to the oscillation direction. A wave moves energy rather than moving mass within the direction of propagation.

From the given information;

The direction =

This implies that:  

In the direction

multiply 2kg by latent heat of vap

truck y has a greater velocity than truck x.
