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

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: In series combination of electric bulbs th ebulb of lower power emits more light than that of higher power bulb. Reason: The lower power bulb in series gets more current than the higher power bulb.

Assertion : A beam of white light when passed through a hollow prism cannot give spectrum. Reason : Because refractive index of air inside and outside the prism is same so no refraction and hence no deviation wll take place.

Assertion : Sound waves cannot propagate through vacuum but light waves can. Reason : Sound waves cannot be polarised but light waves can.

Assertion: Photoelectric effect proves the particle nature of light. Reason: Photoemission starts as soon as light is incident on the metal surface, provided frequency of incident light is greater than or equal to the threshold frequency.

Given below are two statements : one is labelled as Assertion A and the other is labelled as Assertion A: An electron microscope can achieve better resolving power than an optical microscope. Reason R : The de Broglie's wavelength of the electrons emitted from an electron gun is much less than wavelength of visible light. In the light of the above statements, choose the correct answer from the options given below:
