Diffraction of Light

 In Young's double slit experiment, a mica slit of thickness $t$ and refractive index $\mathit{\mu }$ is introduced in the ray from the$\mu$ first source S. By how much distance the fringes pattern will be displaced
 

How energy is consereved in double slit interference and single slit diffraction?

Draw and compare the intensity graph of single slit diffraction and double slit interference.

State two differences between double$‐$slit interference and single slit diffraction patterns.

Which one of the following statement is true for both the interference and diffraction?

In a double-slit experiment, two slits are $2 \mathrm{mm}$ apart and the screen is placed $1 \mathrm{m}$ away. Sodium light of wavelength $589 \mathrm{nm}$ is used to observe the fringe pattern. What will be the width of each slit to obtain $10$ maxima of a double-slit pattern within the central maxima of the single slit pattern?

If I_o is the intensity of the principal maximum in the single slit diffraction pattern, then what will be the intensity when the slit width is doubled?

The diffraction fringes obtained by a single slit are of

In a single slit diffraction pattern, a light of wavelength $6000 \stackrel{\mathrm{o}}{\mathrm{A}}$ is used. The distance between the first and third minima in the diffraction pattern is found to be $3 \mathrm{mm}$ when the screen is placed $50 \mathrm{cm}$ away from slits. The width of the slit is ____$\times {10}^{-4} \mathrm{m}$.

Diffraction pattern of a single slit consists of a central bright band which is
