In Young's double -slit experiment butter paper is placed convering one of the slit. How will the interference pattern on a distant screen change if butter paper partially refracts the light through it?

In young's double slit experiment relative intensity at a point on the screen may be defined as ratio of intensity at that point to the maximum intensity on the screen. Light of wavelength 7500overset(@)A A passing through a double slit, produces interference pattern of relative intensity variation as shown in Fig. theta on horizontal axis represents the angular position of a point on the screen (a) Find separation d between the slits. (b) Find the ratio of amplitudes of the two waves producing interference pattern on the screen.

Why don't we hav interference when two candles are placed close to each other and the intensity is seen at a distant scree? What happens if the candles are replaced by laser sources?

Two monochromatic light waves of equal intensities produce an interference pattern. At a point in the pattern, the phase difference between the interfering waves is pi//2 rad. Express the intensity at this point as a fraction of the maximum intensity in the pattern.

In a Young's double slit experiment, light of 500 nm is used to produce an interference pattern. When the distance between the slits is 0.05 mm, the angular width (in degree) of the fringes formed on the distance screen is close to:

Out of the following, which can be used as coherent sources required to produce interference pattern of light ?

In Young's double slit experiment the two slits are d distance apart. Interference pattern is observed on a screen at a distance D from the slits. A dark fringe is observed on the screen directly opposite to one of the slits. The wavelength of light is
