A beam of light of wavelength λ = 5000Å falling normally on a plane diffraction grating. The 1st order spectrum is derived in a direction making an angle θ1 with the normal (Sin θ1 = 0.25). Determine grating element and the angle θ2 for 2nd order spectrum.
Q. What is dual character of light? Light behaves as particles of energy in the higher energy region as well as as waves in the lower energy region.
