Determine the angular separation betwen central maximum and first order maximum of the difraction pattern due to a single slit of width 0.25 mm,when light of wavelength `5,890 overset@A` is incident on it normally.

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.

In a single slt diffraction pattern,how is the width of cetral bright maximum changed,when light of smaller wavelength is used.Justify you answer.

If I_0 is the intensity of the principal maximum in the singel slit diffraction pattern,then what will be its intensity when the slit width is doubled?

In a Young's double slit experiment,two slits are 1.5 mm apart and a screen in placed at a distance 1.2 m from the plane of the slits .The slits are illuminated with light of wavelength 6,000 overset @A .Find the inimum distance from the central maximum for which the intensity is half of the maximum intensity.

Light of wavelength 550nm is incident as parallel bea on a silt of width 0.1 mm.Find the linear width and the angular width of the principal maxima in the resulting diffraction pattern on a screen kept at a distance of 1.1 m from the slit.Which of these widths would not change,if the screen were moved to a distance of 2.2 m from the slit?

In a single slt diffraction pattern,how is the width of cetral bright maximum changed,when teh slit width is decreased,

In a double slit experiment the distance between the slits is 3 mm and the slits are 2 m away from the screen. Two interference patterns can be seen on the screen one due to light with wavelength 480 nm, and the other due to light with wavelength 600 nm. what is the separation on the screen between the fifth order bright frings of the two interference patterns?

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?

Light of wavelngth 600 nm is incident on a single slit of width 0.5 mm at normal incidence.Calculate the separation between two dark bbands on either side off the central maximum,if the diffration pattern is observed on a screen placed at 2 m from the slit.
