Assertion : A laser beam 0.2 W power can drill holes through a metal sheet, whereas 1000 W torch-light cannot. Reason : The frequency of laser light is much higher than that of torch light.

Assertion : If the light from an ordinary source passes through a polaroid sheet, its intensity is reduced by half. Reason : The electric vectors associated with the light wave along the direction of the aligned molecules get absorbed by polaroid.

Assertion : The number of electrons ejected from a metal surface depend upon the frequency of light. Reason : There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.

Assertion : The threshold frequency of photoelectric effect supports the particle nature of light. Reason : If frequency of incident light is less than the threshold frequency, electrons are not emitted from metal surface.

Assertion : If the frequency of the incident light on a metal electrons is more than doubled. Reason : The metal will provide additional energy to the emitted photoelectron for light of higher frequency than for lower frequency.

Assertion : Photoelectric effect is the phenomenon of emission of photon by metal when illuminated by light of suitable frequency. Reason : An electron beam carries sufficient energy to release photons from the metal.

Assertion :- When monochromatic light is incident on a surface separating two medium, the reflected and refracted light has same frequency as incident light. Reason :- Reflection and refraction arise through interaction of incident light with atoms of matter and atoms act as oscillator which takes up frequency of incident light and undergoes forced oscillation and scatters light of same frequency.

This question has statement - 1 and statement - 2 of the four choice given after the statements choose the one that best describes the two statements statement - 1 : A metallic surface is irradiated by a monochromatic light of frequency v gt v_(0) (the threshold frequency). The maximum kinetic energy and the stopping potential are K_(max) and V_(0) respectively if the frequency incident on the surface is doubled , both the K_(max) and V_(0) are also doubled statement - 2 : The maximum kinetic energy and the stopping potential of photoelectron emitted from a surface are linearly dependent on the frequency of incident light

Assertion : There is no dispersion of light refracted through a rectangular glass slab. Reason : Dispersion of light is the phenomenon of splitting of a beam of white light into its constituent colours.

A horizontal cylinderical tank (6)/(pi)m in diameter is half full of water. The space above the water is filled with a pressurized gas of unknown refractive index. A small laser can move along the curved bottom of the water and aims a light beam towards the centre of the water surface. When the laser has moved a distance s=1m or more (measured from curved face) from the lowest point in water, no light enters the gas. The refractive index of gas is (mu_("water") = 4//3)
