If torch is used in place of monochromatic light in Young's experiment what will happen

A

fringe will appear for a moment and then it will disppear

B

fringe will occure as from monochromatic source

C

only bright fringes will appear

D

no fringe will appear

Text Solution

Verified by Experts

The correct Answer is:
D
When the torch is used in the Young's experiment, the fringe will overlap, due to the different colours in a very confusing ways. So, it will not give a clear interference pattern. Hence, no fringe will appear/

If a torch is used in place of monochromatic light in Young's experiment what will happen?

The maximum intensity in Young.s double slit experiment is I_0 . Distance between slits is d= 5 lambda , where lambda is the wavelenght of the monochromatic light used in the experiment. What will be the intensity of light in front of one of the slits on a screen at a distance D= 10d .

A parallel beam of monochromatic light is used in a Young's double slit experiment. The slits are separated by a distance d and the screen is placed parallel to the plane of the slits. Show that if the incident beam makes an angle theta=sin^-1(lamda/(2d)) with the normal to the plane of the slits, there will be a dark fringe at the centre Po of the pattern.

Assertion : When a thin transparent sheet is placed in front of both the slits of Young's experiment, the fringe width will remains same. Reason : In Young's experiment, the fringe width is directly proportional to wavelength of the source used.

What happens to the interference pattern if the two slits in Young's experiment are illuminated by two independent sources such as two sodium lamps S and S' as shown in figure

In Young's double slit experiment if monochromatic light is replaced by white light

In Young.s double slit experiment, using monochromatic light L_1 of wavelength 700 nm, 10th bright fringe was obtained at a certain point P on a screen. Which bright fringe will be obtained at the same point P if monochromatic light of wavelength 500 nm is used in place of L_1 (No other alterations were made in the experimental set up).

What happens by the use of white light in Young's double slit experiment:

In a Young's double slit experiment using monochromatic light, the fringe pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 and thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the slits and screen is doubled. It is found that the distance between successive maxima now is the same as observed fringe shift upon the introduced of the mica sheet . Calculate the wavelength of the monochromatic light used in the experiment .

In a Young's double slit experiment using monochromatic light, the fringe pattern shifts by as certasin distance on the screen when a mica sheet of refractive inde 1.6 and thickness 1.964 micron (1 micron =10^-6m) is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the screen and the slits is doubled. It is found that the distance between the successive maxima now is the same as the observed frige-shift upon the introduction of the mica sheet. Calculate the wavelength of the monochromatic light used in the experiment.
