Embibe Experts Solutions for Chapter: Wave Optics, Exercise 1: Exercise 1

Two straight and narrow slits $0.3 \mathrm{mm}$ apart are illuminated by a monochromatic source of wavelength $5.9\times {10}^{-7} \mathrm{m}$. Fringes are obtained at a distance of $0.30 \mathrm{m}$ from the slit. The width of the fringe is

If two line slits are Illuminated by a wavelength $5\times {10}^{-7} \mathrm{m}$ and the distance between two bright fringes is $0.005 \mathrm{m}$ on a screen $1 \mathrm{m}$ away, then the distance between the slits is

The length of the optical path of two media in contact of length $d_1$ and $d_2$ of refractive indices ${\mu }_1$ and ${\mu }_2$, respectively, is

For radiation of $9 \mathrm{GHz}$ passing through air. The number of waves passing through $1 \mathrm{m}$ length is

A light beam travelling in the $x-$direction is described by the electric field $E_{\mathrm{y}}=\left(300 \mathrm{V} {\mathrm{m}}^{-1}\right)\sin \left[\omega \left(t-\frac{x}{c}\right)\right]$. The maximum magnetic field is

An electromagnetic radiation of frequency $v$, wavelength $\lambda$ travelling with velocity $c$ in air enters a glass slab of refractive index $\mu$. The frequency, wavelength and velocity in the glass slab will be, respectively,

The wavelength of electromagnetic waves employed for space communication lie in the range of-

The sound waves after being converted into electrical waves are not transmitted as such because -
