Electric field component of an EM radiation varies with time as E = a (cos$$\omega$$₀t + sin$$\omega$$t cos$$\omega$$₀t), where a is a constant and $$\omega$$ = 10¹⁵ s^$$-$$1, $$\omega$$₀ = 5 $$\times$$ 10¹⁵ s^$$-$$1. This radiation falls on a metal whose stopping potential is $$-$$2 eV. Then, which of the following statements is/are true ? (h = 6.62 $$\times$$ 10^$$-$$34 J-s)

A point source of light is used in an experiment of photoelectric effects. If the distance between the source and the photoelectric surface is doubled, which of the following may result?

Electrons are emitted with kinetic energy T from a metal plate by an irradiation of light of intensity J and frequency v. Then, which of the following will be true?

The distance between a light source and photoelectric cell is d. If the distance is decreased to $${d \over 2}$$, then
