A diffraction pattern is obtained by using a beam of red light. What will happen if red light is replaced by blue light?
Solution
If the red light replaced by blue light then the diffraction maxima band becomes narrow because the diffraction band depends on the wavelength and here blue light has less wavelength than red light. Therefore, the diffraction pattern obtained will crowded as compared to previously.
