What is angular width of central maxima?

Light of wavelength 5.4 xx 10^(-5)cm passes through a silt 0.12 cm wide and forms a diffraction pattern on a screen 2.7 m away. What is the width of the central maxima?

A parallel beam of monochromatic light falls normally on a single narrow slit. How does the angular width of the central maximum in the resulting diffraction pattern depend on the wavelength of the incident light?

Angular width of centrl maximum in the Fraunhofer diffraction pattern of a slit is measured.The slit is iluminated by igth of wavelength 6,000 overset@A .When the slit is illuminated by light of another wavelength,the angular width decreases y 30%.Calculate the wavelength of this light. The same decrease in the angular width of centrl maximum is obtained ,when the original appartus is immersed in a liquid.Fin refractive index of the liquid.

One method of prodocing two in - phase point sources of light for interference is to form two images of a point source by means of the two halves of a lens,which has been split along a diameter[Fig.6.17]. A screen placed perpendicular tot he principal axis and 80 cm from the mage sources.What is the width of central maxima formed on the screen,if the wavelength of the light used is 5.4 xx 10^(-5) cm ?

A parallel beam of monochromatic light falls normally on a single narrow slit. How does the angular width of the principal maxima in the resulting diffraction pattern depend on width of the slit?

The light of wavelength 600 nm is incident normally on a slit of width 3 mm. Calculate the linear width of central maximum on a screen kept 3 m away from the slit.

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.

Discuss fully diffraction at a single slit and derive the relation for the linear width of central maximum.

The light of wavelength 6,000 overset @A falls normally on a slit odf width 2 mm.Calculate the linear width of central mximum on a screen kept 4 m away from teh slit.
