What are the wavelength and frequency of the reflected light? For what angle of incidence is the reflected ray normal to the incident ray? The reflected wavelength is.

What are the wavelength and frequency of the reflected light? For what angle of incidence is the reflected ray normal to the incident ray? The wavelength and frequency of incident light is the same as that of reflected ray. When reflected ray is normal to incident ray, the sum of the angle of incidence, ang.

Treat the speed of light as , miles per second. The first step is always to write out the data. All that we need to know is in the problem:. The third step is unit conversion. The units are fine just the way they are in this problem, so we can skip this step. Once we get our answer in miles per sec, we will have to convert that to miles per hour. In order to make the red light appear green, we would have to travel at almost one-quarter of the speed of light, ,, miles per hour!
