2. (a) Laser light is commonly used in optical measurement
systems. List the five properties of laser light that make it
particularly suited to this application.
(b) (i) Define: *Intensity
*Wavelength
(ii) Consider light in the blue/green region of the spectrum. If
the wavelength of the light is 500nm, calculate its frequency.
(iii) Interferometers are used to generate the structured light
pattern required for non-contact metrology applications. Explain,
including diagrams where appropriate, the layout of a Michelson
Interferometer and describe five possible applications of such a
device.
