A Young's double slit experiment is performed with white light.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D

The change in path difference due to the two slabs is `(mu_1-mu_2)t` (as in problem No. 16) For having a minimum at P, the path difference should change by `1/2`
So, `lamda/2=(mu_1-mu_2)t`
`rarr t=lamda/(2[mu_1-mu_2])`

If young's double slit experiment is performed in water

Young's double slit experiment is first performed in air and then in a medium other than air. It is found that 8^(th) bright fringe in the medium lies where 5th dark fringe lies in air .The refractive index of the medium is nearly:

A double slilt experiment is performed with sodium (yellow) light of wavelength 589.3 nm and the interference pattern is observed on a screen 100 cm away. The tenth bright fringe has its centre at a distance of 12 mm from the central maximum. Find the separation betwen the slits.

The width of one of the two slits in a Young's double slit experiment is double of the other slit. Assuming that 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.

If the source of light used in a young's double slit experiment is changed from red to violet

The intensity of the light coming from one of the slits in a Young's double slit experiment is double the intensity from the other slit. Find the ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed.

A transparent paper (refractive index = 1.45) of thickness 0.02 mm is pasted on one of the slits of a Young's double slit experiment which uses monochromatic light of wavelength 620 nm. How many fringes will cross through the centre if the paper is removed ?

In Young 's double slit experiment the distance between the slits and the screen is doubled the separation between the slits is reduced to half. As a result the fringe width.

In Young's double slit experiment using monochromatic light of wavelength lamda , the intensity of light at a point on the screen where path difference is lamda is K units. What is the intensity of light at a point where path difference is (lamda)/3 ?

If the separation between the slits in a Young's double slit experiment is increased. What happens to the fringe width? If the separation is increased too much will the fringe pattern remain detectable?
