Question

How are sound and light similar? How are they different?

Answer 1

They are
Both forms of energy that travels in waves

They are different because:
Sound is a mechanical wave
Light is a transverse wave
Light is way faster
Sound has to travel through a medium (substance) but light is electro magnetic (meaning it doesn’t need to travel through anything and it can travel a vacuum e.g light travel in space)

Answer 2

Sound requires a medium to move through; light does not.

Sound and light are similar in that both are forms of energy that travel in waves.

Step-by-step explanation:

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.

Light waves DO NOT require a medium, they travel fastest in empty space; Sound waves REQUIRE a medium, they travel fastest in dense material like solids. Sound is a longitudinal wave.
