Light enters from air into glass having refractive index 1.50. What is the speed of light in glass? The speed of light in vacuum is 3 x 108 ms-1.
Given,n=1.5 and the speed of light in vacuum, c = 3x 108 ms-1. We know that the refractive index is given by the expression n =c/v where c is the...

A mixture of light, consisting of wavelength 590nm and an unknown wavelength,
(c) : For interference, by Young’s double slits, the path difference xd/D= nλ for bright fringes and xd/D = (2n +1)λ/2 for getting dark fringes. The central fringes when x =...

The light emitted in the transition n = 3 to n = 2 in hydrogen is called Hα light. Find the maximum work function
n1 = 2, n2 = 3 Energy possessed by Hα light = 13.6 (1/n12 – 1/n22) = 13.6 x (1/4 – 1/9) = 1.89 eV. For Hα light to be able to emit photoelectrons from a metal...

What is Perfectly Elastic Supply? When price falls by Rs.2 per unit, supply falls from 100 units to 80 units.
Es = P/Q x ΔQ/ΔP = P/100 x -20/-2 = 400/20 = Rs. 20
