A slit 4.0 cm wide is irradiated with microwaves of 2.0 cm. Find the angular spread of central maximum 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.

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) Explain two features to distinguish between the interference pattern in Young's double slit experiment with the difference pattern obtained due to a single slit. (b) A monochromatic light of wavelength 500 nm is incident normally on a single slit of width 0.2 nm of produce a diffraction pattern. Find the angular width of the central maximum obtained on the screen. Estimate the number of fringes obtained in Young's double slit experimental with fringe width 0.5 mm , which can be accommodated within the region of total angular spread of the central maximum due to single slit.

A monochromatic light of wavelength 500 nm is incident normally on a single slit of width 0.2 mm to produce a diffraction pattern. Find the angular width of central maximum obtained on the screen, 1 m away. Estimate the number of fringes obtained in YDSE with fringe width 0.5 mm , which can be accommodated within the region of total angular spread of the central maximum due to a single slit.

A coherent parallel beam of microwaves of wavelength lambda = 0.5 mm falls on aYoung's double- slit apparatus. The separation between the slits is 1.0 mm. The intensity of microwaves is measured on a screen placed parallel to the plane of the slits at a distance of 1.0 m from it as shown in Fig. 2.42. If the incident beam makes an angle or 30^(@) with the x-axis (as in the dotted arrow shown in the figure), find the y-coordinates of the first minima on either side of the central maximum.
