Population inversion
What is the effective distance between the source of light and the screen in Fraunhofer Diffraction?
Focal length of the convex lens
Less than Focal Length of the convex lens
Greater than the focal length of the convex lens and less than infinite
Infinite
How shall the pattern change when white light is used in Fraunhofer Diffraction instead of monochromatic light?
The pattern will no longer be visible
The shape of the pattern will change from hyperbolic to circular
The colored pattern will be observed with a white bright fringe at the center
The bright and dark fringes will change position
A screen is placed 2m away from the lens to obtain the diffraction pattern in the focal plane of the lens in a single slit diffraction experiment. What will be the slit width if the first minimum lies 5 mm on either side of the central maximum when plane light waves of wavelength 4000 Å are incident on the slit?
0.16 mm
0.26 mm
0.36 mm
0.46 mm
If the Fresnel’s distance is a, then what should be the distance of the screen from the slit, d, such that ray optics is no longer valid?
D > a
D < a
D = a
No relation between d and a
