4I0

Explanation:

When the slit width is doubled the energy falling per sec on the screen is doubled but angular width of central maxima (Δθ=2λ/b) is halved. Hence intensity of the central maxima will be 4I0

In a plane diffraction the main maximum strength is:

  • The grating rigidity provides a maximum rigid equal to the square of the number of illuminated spaces.
  • Increasing the number of slits not only makes the size of the diffraction sharper, but also more rigid.
  • In Optics, diffraction grating is an optical component with a periodic structure that divides light into several beams running in different directions.
  • The resulting color is a type of structural color.
  • The direction or diffraction angles of these poles depend on the incident angle (bright) to the degree of diffraction, space or distance between adjacent separated elements.
