Evaluate each of the following as true or false?
Monochromatic light has one wavelength.
Fluorescent lights are a source of coherent light.
Destructive interference occurs when two waves differ in phase by 180 degrees.
A phase difference of 360 degrees is the same as a path dissimilarity of one half wavelengths.
The reflected component of light traveling from one medium into another of lower refractive index will not undergo a phase change relative to the incoming light.
