Which phenomenon causes the formation of bright and dark fringes in Newton’s Rings?
Interference of reflected light.
What is the condition for constructive interference in Young’s Double Slit Experiment?
Path difference = nλ, where n is an integer.
In YDSE, what happens to fringe width if the wavelength is doubled?
Fringe width also doubles.
Which instrument uses a movable mirror to measure small path differences?
Michelson’s Interferometer.
What kind of wavefront does a point source produce in interference experiments?
Spherical wavefront.
Name the device that uses interference to precisely measure wavelengths of light.
Michelson’s Interferometer.
Why do we see circular fringes in Newton’s ring setup instead of straight lines?
Due to symmetrical air film between lens and glass plate.
What is the formula for fringe width in Young's Double Slit Experiment?
β = λD/d (where D = screen distance, d = slit separation)
What changes in Michelson’s interferometer when the mirror is moved by 1 micron?
Two fringes shift (as path difference changes by 2 microns).
Which type of interference (constructive or destructive) results in a dark fringe?
Destructive interference.
