Which of the following helps support the argument that light behaves like a particle?

ASound, which travels in waves, can't travel through a vacuum.
BInterference is observed with light.
CDiffraction is observed with light.
DUnlike sound, light waves don't need a medium to self-propagate

Verified Answer :

Sound, which travels in waves, can't travel through a vacuum. 

As there is no matter in vacuum then sound cannot be transmitted. But the transmission of light is quite different, its particle and wave nature is well suited for travel in vacuum.

The correct answer to the question is : D) Unlike sound, light waves don't need a medium to self-propagate

EXPLANATION:

Before coming into any conclusion, first we have to understand the nature of sound and light.

A sound wave is a longitudinal wave which requires a medium for its propagation.  It can not move in space as space contains no material medium for its propagation.

Light is normally considered as electromagnetic wave which does not require any medium for its propagation. It can travel in space also.

The interference and diffraction can not be explained by the particle nature of light.

Hence, the argument that partially support that light behaves just like a particle is the last statement i.e Unlike sound, light waves do not need a medium to self-propagate.
