Question

In what ways are sound and light waves similar? In what ways are sound and light waves different?

Answer 1

Similarities:
Both sound waves and light waves can experience interference due to superposition principle.
Sound and light transmit the energy that travel in waves.
They both have properties of waves: wavelength, frequency and amplitude.
Differences:
Sound waves require the medium, but light waves do not.
The speed of light is higher than speed of sound.
Sound waves are longitudinal waves. Light waves are transverse waves.
