## sidsiddhartha one year ago what is the difference between time and space harmonics ?

The answer is somewhat in the title. Harmonics implies a sinusoidal variance. For time harmonics, this means a sinusoidal variance in time, and for space harmonics one in space accordingly. In time harmonics this time variance would depend on angular frequency $\omega = 2*\pi*f$ while for space it would depend on spatial frequency = $k = 2*\pi/\lambda$
