A monochromatic ray of light passes from air to glass. The wavelength of light in air is λ, the speed of light in air is

Speed, intensity and wavelength

(a) Air (its refractive index is less than that of water) (b) Glass (its refractive index is more than that of water)

Refractive index of water, μ w = 1.33 Refractive index of air, μ a = 1.0003 Refractive index of glass, μ g = 1.5 This implies that μ a < μ w <...

(i) i2 = i1 (ii) Angle of deviation is minimum Explanation: In minimum deviation position, the refracted ray inside the prism travels parallel to it if the prism is equilateral and the...

B made of flint glass. Because it has higher refractive index.

Speed of light increases with increase in the wavelength.

False A ray of light when passes from glass to air, bends towards the normal.

electrons are transferred from the glass rod to the silk
