Light with wavelength `lambda` falls on a diffracting grating at right angles. Find the angular dispersion of the grating as a function of diffraction angle `theta`.

What is a diffraction grating?

Light with wavelength 530nm falls on a transparent diffraction grating with period 1.50 mu m . Find the angle, relative to the grating normal. At which the Fraunhofer maximum of highest order is observed provided the light falls on the grating (a) at right angles, (b) at the angle 60^(@) to the normal.

A beam of monochromatic light of wavelength lambda falls normally on a diffraction grating of line spacing d. If theta is the angle between the second-order diffracted beam and the direction of the incident light, what is the value of sin theta ?

Demonstrate that when light falls on a diffracting grating at right angles, the maximum resolving power of the grating cannot exceed the value l//lambda , where l is the width of the grating and lambda is the wavelength of light.

A plane light wave with wavelength lambda falls normally on a phase diffraction grating whose side view is shown in Fig. The grating is cut on a glass plate with refractive index n . Find the depth h of the lines at which the intensity of the central Fraunhofer maximum is equal to zero. what is in this case the diffraction angle corresponding to the first maximum?
