Practice Questions for Wave Optics

If in a Young's double slit experiment the distance between the two slits is halved and the distance between the slits and the screen is doubled, then the fringe width:

What happens to the wavelength (λ) and frequency (ν) of light when it propagates from a rarer medium to a denser medium?

In the Davisson-Germer experiment, the intensity of the scattered electron beam is maximum at which of the following scattering angles?

Most ordinary gases do not show dispersion with visible light. This is because the velocities of propagation of waves of different wavelengths of visible light in these gases are ________. (Velocity of light in vacuum is c)

If an opaque object placed in the path of light becomes very small, light has a tendency to bend around its edges instead of moving in a straight line. This phenomenon is known as:

Suppose to obtain a diffraction pattern a student uses a violet-colored beam of light. If the student replaces the violet light with green light, then:

The reciprocal of wavelength (λ) is defined as which of the following physical quantities?

The fringe width observed in Young's double-slit experiment is β. If the frequency of the light source is doubled while keeping other parameters constant, the new fringe width will become:

Two light beams having intensities I and 9I interfere to produce a fringe pattern on a screen. The phase difference between the beams is π/2 at point P and π at point Q. The difference between the resultant intensities at P and Q will be:

Two coherent light beams of intensity I and 4I produce an interference pattern. The intensity at a point where the phase difference is zero will be:

Two light sources are said to be coherent if they produce waves:

If two identical coherent waves, each of intensity I, undergo constructive interference at a point, the resultant intensity at this point will be:

In a Young's double slit experiment, a student observes 8 fringes in a certain segment of a screen when a monochromatic light of 600 nm wavelength is used. If the wavelength of light is changed to 400 nm, then the number of fringes he would observe in the same region of the screen is:

Two coherent light sources having intensities in the ratio of 2x produce an interference pattern. The ratio Imax - IminImax + Imin will be:

In a Young's double slit experiment, the width of one of the slits is three times the other slit. Assuming that the amplitude of light coming from a slit is proportional to the slit-width, find the ratio of the maximum to the minimum intensity in the interference pattern.

For light diverging from an ideal point source in an isotropic medium, which of the following is correct?

Consider the Fraunhofer diffraction pattern for a small circular pinhole. As the size of the hole is increased, how do the size and intensity of the central bright disc change?

Consider sunlight incident on a pinhole of width 103 Å. The diffraction image of the pinhole seen on a screen shall be:
