Embibe Experts Solutions for Exercise 2: Assigment

When two coherent waves of equal amplitude $a$ having constant phase difference $\varphi$ at a point, are superimposed, then amplitude of resultant wave will be $2a$_____$\left(\frac{\varphi }{2}\right)$.

The _____ width in YDSE is equal to $\frac{\lambda D}{d}$ . 

For a single slit of width $a$, the first _____ occurs at an angle of $\frac{\lambda }{a}$ .(minima/maxima)

_____ distance $Z_F$ is equal to $\frac{a^2}{\lambda }$, where, $\lambda$ is wavelength and $a$ is slit width.

Polarised light can be produced by scattering through an angle _____ $°$(in degrees) in the earth's atmosphere.

If an interference pattern, the ratio of maximum and minimum intensity is $9 : 1,$ then the ratio of amplitudes of interfering waves is

YDSE is performed in air and then with same setup performed in water, the fringe width in water

In YDSE, slits are $0.589 \mathrm{mm}$ apart. If a sodium vapour lamp of wavelength $589 \mathrm{nm}$ is used, then angular width of central maxima is
