ANNA UNIVERSITY 'PART‒B'
QUESTIONS
1.
Explain with theory, air wedge method of determining the radius of a thin wire.
2.
Explain the construction, types of fringes and applications of Michelson
interferometer.
3.
Describe Michelson interfermeter and explain the formation of fringes in it.
Discuss how this interferometer is used to find the wavelength of monochromatic
light. Also explain how the thickness of a thin transparent film or plate is
determined using this.
4.
Illustrate with figures, the different types of fringes formed in Michelson's
interferometer and the corresponding positions of mirrors for them.
5.
Describe the construction and working of Michelson's Interferometer.
How
is the wavelength of a monochromatic light source determined using the
Michelson's interferometer.
6.
Describe the construction and working of Michelson's interferometer. Also
explain, with necessary theory, a laboratory experiment of finding the
wavelength of a monochromatic of light using Michelson's interferometer.
7.
Explain how the wavelength of monochromatic source of light can be
experimentally determined using a Michelson's Interferometer.
8.
Explain the formation of interference fringes in an air‒wedge shaped film. How
is the thickness of the wire determined by this method?
9.
Michelson's Interferometer and explain the formation of the fringes.
10.
Describe an experiment to determine the thickness of a thin wire by forming an
Air wedge.
