Which of the following 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.

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.

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.

you probably know the answer. stop asking stupid questions and making me waste my time. j.k. ; )   b.t.w. what are three ratios equivalent to 5 : 11? thx

d.

thist title points out that you are explaining the nature of the u.s. government. it is the most specific. a representative government consists of a government where decisions are taken according to a voting system. the most essential aspect of a representative government is found in the different structures where voting rights are granted to different groups of people. for example, voting for governor, mayor, president, local police chief etc.
