Question

From the following, number of options which relate to particle nature are:
(a) Interference
(b) Diffraction
(c) Photoelectric effect
(d) Black body radiation
(e) Planck's equation, $E=hv$

(f) Einstien's equation$E=m{c}^2$

Answer 1

Interference and diffraction are both related to wave nature of light as this concept is based on the superimposition of waves.Photoelectric effect and Planck's equation is based on the particle nature of light (energy packets). $E=m{c}^2$ is also based on particle nature of light as we can find the mass of light from its energy. Black body radiation is based on the wave natue as radiation concept is purely wave-based.

Hence, the number of options is 3.
