Two coherent plane waves of identical frequency, polarization and intensity $\left(I\right)$ interfere at a point where they differ in phase by $60°$. What is the resulting intensity?

Two beams of monochromatic light with intensities $64 \mathrm{mW}$ and $4 \mathrm{mW}$ interfere constructively to produce an intensity of $100 \mathrm{mW}$. If one of the beams is shifted by an angle $\theta ,$ the intensity is reduced to $84 \mathrm{mW}$. The magnitude of $\theta$ is

Interference fringes are obtained in a Young double slit experiment using beam of light consisting two wavelengths $500 \mathrm{nm}$ and $600 \mathrm{nm}$. Bright fringes due to both wavelengths coincide at $2.5 \mathrm{mm}$ from the central maximum. If the separation between the slits is $3 \mathrm{mm}$, then the distance between the screen and plane of the slits is

In a Young's double slit experiment, a thin sheet of refractive index $1.6$ is used to cover one slit while a thin sheet of refractive index $1.3$ is used to cover the second slit. The thickness of both sheets are same and the wavelength of light used is $600 \mathrm{nm}$. If the central point on the screen is now occupied by what had been the ${10}^{\text{th }}$ bright fringe $\left(\mathrm{m}=10\right)$, then the thickness of covering sheets is

What would be the angular separation between the consecutive bright fringes in Young's double slit experiment with blue green light of wavelength $400 \mathrm{nm}?$ The separation between the slits is $0.001 \mathrm{m}.$

In Young's double slit experiment using monochromatic light of wavelength $\lambda ,$ the intensity of light at a point on the screen where the path difference is $\frac{1}{3}$, is $I_{0.}$ What is the intensity of light at a point where the path difference is $\lambda$ ?

The fringe widths are found to be ${\omega }_1$ and ${\omega }_2$ respectively if a Young's double slit experiment is performed in medium of refractive index $n_1$ and $n_2$ respectively. The correct statement is
