When both the slits are opened, we can see interference pattern. Why?

Text Solution

Verified by Experts

Due to th superposition of light waves coming from the two slits. Constructive and destructive interference are taking place.

In young's double slit experiment , the slits are 2mm apart and are illuminated by photons of two wavelength lambda_1=12000overset@A and lambda_2=10000 overset@A . At what minimum distance from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?

In Young's double slit experiment, the slits are 2 mm apart and are illuminated with a mixture of two wavelength lamda_0 = 750 nm and lamda = 900 nm. What is the minimum distance from the common central bright fringe on a screen 2 m from the slits where a bright fringe from one interference pattern coincides with a bright fringe from the other?

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.

Two slits in Young's experiment have widths in the ratio 1:25 The ratio of intensity at the maxima and minima in the interference pattern (I_(max))/(I_(min)) is .

In a Young's double slit experiment the separation between the slits is 0.10 mm, the wavelength of light used is 600 nm and the interference pattern is observed on a screen 1.0 m away. Find the separation between the successive bright fringes.

White light is passed through a double slit and interference pattern is observed on a screen 2.5 m away. The separation between the slits is 0.5 mm. The first violet and red fringes are formed 2.0 mm and 3.5 mm away from the central white fringe. Calculate the wavelengths of the violet and the red light.
