Light and sound - reflection and refraction

Light and sound - reflection and refraction

Light and sound both travel as waves, but they are not identical.

When white light passes from air into a triangular prism, it refracts into the colours of the rainbow.

Sound waves and light waves change speed when they pass across the boundary between two substances with different densities such as air and glass.

Diffraction is the spreading out of waves when they pass through a gap.

Both angles are measured from the…
