Question

Which of the following helps support the argument that light behaves like a particle? A. Sound, which travels in waves, can't travel through a vacuum. B. Interference is observed with light. C. Unlike sound, light waves don't need a medium to self-propagate. D. Diffraction is observed with light.

Answer 1

Answer:

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

Explanation:

Light as a particle consists of particles called protons which carry some amount of energy that are reflected by objects when emitted.

Light as a wave can travel through a vacuum but sound, which travels in waves, can't travel through a vacuum.

Answer 2

Answer:D. DIFFRACTION IS OBSERVED WITH LIGHT

Explanation: Light has a dual nature it can exist as both a wave and particle, as a wave you see light in the electromagnetic spectrum from visible light,XRays,Gamma rays infrared. etc the path a light follows can be slightly distorted by an obstruction causing it particles to move in another direction. sound exists as a photon as shown by Schrodinger's equation and theory, and in Quantum physics.
