Question

Sound and light waves both ______.

Options

• have similar wavelength

• obey the laws of reflection

• travel as longitudinal waves

• travel through vacuum

Answer 1

Sound and light waves both obey the laws of reflection.

Explanation:

Both sound and light waves obey the laws of reflection, so the angle of incidence is equal to the angle of reflection. They differ in other properties: light can travel through vacuum, whereas sound requires a material medium.
