When a monochromatic light of wavelength and amplitude (E) is incident from vacuum into a medium with a complex refractive index (n=1 + i), describe how each real and imaginary part of the refractive index affects the light in the medium.
The amplitude of a wave traveling on a string is 0.250 m. The 8.50-Hz wave is traveling in the positive x-direction at a wave speed of 17.0 m/s. Assume this wave is as a sinusoidal wave. If the correct time-dependent wave function for the wave is 0.250sin(3.14(x−ct)+ϕi), then determine the parameter c for the expression.

A traveling wave is given by the expression y = 0.30 sin (0.49πx + 0.90πt) m . What is the group velocity of the wave? What is the instantaneous displacement of the wave at x = 0.7 m and t = 0.2 s
Light, radiant heat (infrared radiation), X rays, and radio waves are all examples of traveling electromagnetic waves. Electromagnetic waves comprise combinations of electric and magnetic fields that are mutually compatible in the sense that the changes in one generate the other. The simplest form of a traveling electromagnetic wave is a plane wave. For a wave traveling in the x direction whose electric field is in the y direction, the electric and magnetic fields are given by Ē = E,...
