Embibe Experts Solutions for Exercise 1: EXERCISE 10.1

Widths of two slits in Young's experiment are in the ratio $4: 1$. What is the ratio of the amplitudes of light waves from them?

Green light of wavelengths $100 \mathrm{\AA }$ from a narrow slit is incident on a double slit. If the overall separation of $10$ fringes on a screen $200 \mathrm{cm}$ away is $2 \mathrm{cm}$, find the slit separation

In $YDSE$, the phase difference between two coherent sources is $\frac{\pi }{3}$ and constant. The intensity at a point which is at equal distance from the sources is $\left(I_0\right.$ is maximum intensity$)$

Young's double slit experiment is made in a liquid. The tenth bright fringe in liquid lies in screen where $6^{\mathrm{th} }$dark fringe lies in vacuum. The refractive index of the liquid is approximately

In Young's double slit experiment the intensity of light at a point on the screen where path difference is $\lambda$ is $I$. If intensity at another point is $\frac{I}{4}$, then possible path differences at this point are

Four waves are represented as
$y_1=20\sin \left(40\pi t\right)$

$y_2=30\sin \left(40\pi t\right)$

$y_3=30\cos \left(20\pi t\right)$

$y_4=30\sin \left(10\pi t\right)$ Which of the waves can produce interference?

The light waves having displacements $y_1=10\sin (\omega t-kx)$ and $y_2=5\sin (\omega t-kx+\varphi )$ interfere. The ratio of maximum to the minimum intensity of light in the interference pattern is
