  ### What is Diffraction Grating?
  
  Diffraction Grating is a wave phenomenon that occurs when a light hits an obstacle with uniformly distributed apertures. Then, the ray gets diffracted and each of them goes into a slightly different direction. We can witness the effects of diffraction only if the spacing between apertures is larger than the wavelength of incident ray.
  
  ### Diffraction Grating Formula
  
  If the incident light ray is perpendicular to grating you can use the diffraction grating formula to find the direction in which the rays are diffracted. The Diffraction Grating Equation is a * ╬╗ = d * sin(╬ÿΓéÉ)
  
  • Where ╬╗ is the incident ray wavelength
  • d is the grating spacing
  • ╬ÿΓéÉ is the angle between initial and diffracted direction of light for ray a
  • a is an integer = 1, 2, 3......
  
  If the incident ray meets the apertures at an angle ╬ÿΓéÆ then you need to include it too in your calculations i.e. a * ╬╗ = d * [sin(╬ÿΓéÆ) + sin(╬ÿΓéÉ)]
  
  If the incident ray is at an angle of 30┬░ the equations for first three diffracted images becomes as follows
  
  ╬╗ = d * [0.5 + sin(╬ÿΓéü)]
  
  2╬╗ = d * [0.5 + sin(╬ÿΓéé)]
  
  3╬╗ = d * [0.5 + sin(╬ÿΓéâ)]
