what will happen if Plano convex lens is replaced by mirror in newton's ring experiment

At what angle will 510-nm light produce a second-order maximum when falling on a grating whose slits are 1.00 x 10-3 cm apart?

If a diffraction grating produces a third-order bright spot for red light (of wavelength 700 nm) at 65.0° from the central maximum, at what angle will the second-order bright spot be for violet light (of wavelength 400 nm)?

Monochromatic light of wavelength 592 nm from a distant source passes through a slit that is 0.0290 mm wide. In the resulting diffraction pattern, the intensity at the center of the central maximum (θ= 0°) is 4.00 x 10-5 W/m2. What is the intensity at a point on the screen that corresponds to θ = 1.20°?

 Calculate the frequency of a pendulum if it makes 16 complete cycles in a time of 24.4 seconds.

Monochromatic light from a distant source is incident on a slit 0.750 mm wide. On a screen 2.00 m away, the distance from the central maximum of the diffraction pattern to the first minimum is measured to be 1.35 mm. Calculate the wavelength of the light.

For a diffraction grating, what is the advantage of (a) many slits, (b) closely spaced slits?

For diffraction by a single slit, what is the effect of increasing (a) the slit width, (b) the wavelength?

Compare the mirror equation with the thin lens equation. Discuss similarities and differences, especially the sign conventions for the quantities involved.

A thin converging lens is moved closer to a nearby object. Does the real image formed change (a) in position, (b) in size? If yes, describe how.
