Wave Optics

Relates the phase difference of two coherent waves to their optical path difference.

Gives the resultant intensity when two coherent waves of intensities I_1 and I_2 interfere with phase difference phi.

Gives the resultant intensity from two equal-intensity coherent sources as a function of phase difference phi.

Gives the maximum and minimum intensities produced by the interference of two coherent waves.

Gives the distance of the n-th bright or dark fringe from the central maximum on the screen in YDSE.

Gives the linear separation between any two consecutive bright or dark fringes on the screen in YDSE.

Gives the angle subtended by one fringe width at the plane of the slits.

Gives the shift of the entire fringe pattern when a transparent sheet of thickness t and refractive index mu is placed in front of one slit.

Gives the condition for the n-th minimum in diffraction from a slit of width a.

Gives the condition for the n-th secondary maximum in diffraction from a slit of width a.

Gives the total angular spread between the first minima on either side of the central maximum in single-slit diffraction.

Gives the linear width of the central diffraction peak on a screen placed at distance D from a slit of width a.

Gives the transmitted intensity when plane-polarized light of intensity I_0 passes through an analyzer oriented at angle theta.

Gives the transmitted intensity when unpolarized light of intensity I_0 passes through a linear polarizer.

Relates the polarizing angle to the refractive index of a dielectric medium when reflected and refracted rays are perpendicular.
