In Young's double slit experiment, if one of the slit is closed fully, then in the interference pattern

A

(a) A bright slit will be observed, no interference pattern will exist

B

(b) The bright fringes will become brighter

C

(c) The bright fringes will become fainter

D

(d) None of the above

Text Solution

Verified by Experts

The correct Answer is:
A
If one of slit is closed then interference fringes are not formed on the screen but a fringe pattern is observed due to diffraction from slit.

In a young's double slit experiment, green light is incident on the two slits. The interference pattern is observed on a screen. Which of the following changes would cause the observed fringes to be more closely spaced?

In a Young's double-slit experiment, green light is incident on the two slits. The interference pattern is observed on a screen. Which one of the following changes would cause the observed fringes to be more closely spaced?

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:

In a Young's double slit experiment, the width of the one of the slit is three times the other slit. The amplitude of the 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.
