A diffraction grating is ruled with 5000 lines per cm. Find the angular position of the second order maximum when
monochromatic light of wavelength 600nm is viewed through the grating.
A grating is ruled with 4000 lines per cm. when monochromatic light is viewed through the grating a second order
image is observed at an angular position of 35°. What is the wavelength of the light used?
A diffraction grating is ruled with 3500 lines per cm. Parallel light of wavelength 600nm is viewed through the
grating. Find:
1. the maximum number of orders of reinforcement that can be seen through the grating.
2. The number of reinforcement maxima that will be observed.
