A slit 5 cm wide when irradiated by waves of wavelength 10 mm results in the angular spread of the central maxima on either side of incident light by about :

A slit 4.0 cm wide is irradiated with microwaves of wavelength 2.0 cm .Fin the angular spread of central maxima assuming incidence normal to the plane of the slit.

A slit 4 cm wide is irradiated with microwaves of wavelength 2 cm. Find the angular spread of central maxima assuming incidence normal to the plane of the slit.

A slit whose width is 5.0 cm is irradiated with microwaves of wavelength 3 cm. What is the angular spread of the central maximum? Assume normal incidence.
