Question

In what ways are sound and light waves similar?

Are they both a form of energy?
Do they both behave as both particles and waves?
Can they both experience interfierence
Do they both move in 3-dimensional space?
Are they both transverse and therefore both can be polarized?

Answer 1

Yes
No; sound does not behave as a particle.
Yes
Yes
No; sound is longitudinal

Answer 2

Energy - yes. Particles and waves -- under ordinary conditions, no. (Sound energy can be quantized as phonons in special circumstances.) Interference - yes. 3-d space - yes. Transverse and polarizable - only light.
