$Discover Physics with free Physics Revision Notes and Physics Calculator: Wavelength Of Monochromatic Light. This image shows the properties and wavelength of monochromatic light formula for the Wavelength Of Monochromatic Light. Use this calculator to calculate the wavelength of monochromatic light passing through a single slit using the conditions of interference, through Young Double-Slit Experiment and using the diffraction grating tool$

Wavelength of monochromatic light passing through a single slit Formula and Calculation

λ₁ = 2 × w × sinθ/2 × N - 1

for the N-th minimum observed on the screen. =

These equations derive from the transformations of the equations used for the conditions of the N-th maximum

w × sinθ = N × λ

and N-th minimum

w × sinθ = 2N - 1/2 × λ

observed on the screen.

Wavelength of monochromatic light passing through a double slit tool Formula and Calculation

λ₂ = a × y/N × D

This formula derives by the combination of the two equations

λ = a × x/D

and

x = y/N

Note: x is the separation between two adjacent similar fringes, i.e. the separation between two maxima or minima observed on the screen.

Wavelength of monochromatic light passing through the diffraction grating tool Formula and Calculation

λ₃ = sinθ/100 × P × N

This formula is obtained by the combination of the formulae

a × sinθ = N × λ

and

a = 1/100 × P

Note: The separation a between two adjacent gratings must be expressed in metres; that's why P is multiplied by 100.
