## Question:

By combining oppositely directed traveling waves of equal amplitudes, we obtain a standing wave. What kind of a wave do we get if the amplitudes are not equal?

## Ray and Wave optics:

Context: Light waves carry energy depending on their frequency. Propagation direction is always a straight line, but the wavefront has different geometries. Light undergoes dispersion, diffraction, and interference. Interference may be either constructive or destructive.
