Solution Summary

Properties of laser beam are determined. Monitoring locations of the crater of a dormant volcano by interferometry are determined.

Solution Preview

Laser beams are highly monochromatic (narrow wavelength band), directional, intense, coherent (meaning all the photons or waves have a constant phase relationship between them). These all make them highly desirable over all other light sources in various situations.

(a) Holography: Coherent Nature. Holographic recording makes use of the principle of interference of light. This property requires, above ...
