Superposition

What is superposition

when two or more waves overlap, the resulting displacement is the sum of their individual displacements of the waves.

What is diffraction?

Spreading of waves into regions of geometric shadows after passing through a narrow slit or past an edge.

simple formular expression for youngs double slit?

The formula for Young's double slit experiment is (x =ax/D ), where ( x) is the fringe width, ( lambda ) is the wavelength of light, ( L ) is the distance from the slits to the screen, and ( d ) is the distance between the slits.

Conditions to produce observable interference in light waves?

The conditions include a coherent light source, which ensures that the waves maintain a constant phase relationship,

The waves have the same amplitude and frequency and travel in the same direction.

What is path difference

Difference between the lengths of paths travelled by two waves before they meet

What is the diffraction pattern of white light

If the white light is incident on the diffraction grating .Each wavelength making up the white light is diffracted by a different angle given by the equation dsinθ = nλ.The net result is a central white fringe surrounded by the different colors, with violet closest and red furthest.

two conditions for the formation of a stationary wave?

Waves move in opposite directions, and they overlap. Waves have the same speed.

Define wavelength of a progressive wave

distance between two adjacent wavefronts.

Formular for length of the string and stationary wave in a closed pipe

L=n(lambda/2)

For minimum frequency of sound to be produces in an open pipe

This mean that the wavelength being longer therefore having two antinodes at each end.
