Question

Evaluate each of the following as true or false?

A laser can be source of monochromatic coherent light.

Destructive interference occurs when two waves overlap with the same phase.

Fluorescent lights are a source of coherent light.

A phase difference of 360 degrees is the same as a path difference of two wavelengths.

The reflected component of light traveling from one medium into another of lower refractive index will not under go a phase change relative to the incoming light.

Answer 1

A laser can be the source of monochromatic coherent light.---->>>>TRUE.

Destructive interference occurs when two waves overlap with the same phase --->>>>>FALSE.

Fluorescent lights are a source of coherent light ----->>>>>TRUE.

A phase difference of 360 degrees is the same as a path difference of two wavelengths. --->>>>TRUE.

The reflected component of light travelling from one medium into another of the lower refractive index will not undergo a phase change relative to the incoming light.------->>>>FALSE.
