Question

Which occurs when a wave is reflected?


The wave can speed up.

The wave’s frequency increases.

The wave can flip upside down.

The wave’s amplitude increases.

Answer 1

When a wave is reflected, **the wave can flip upside down**. This phenomenon is known as an inversion, which occurs when a wave reflects off a boundary that is fixed. The other options (speeding up, frequency increasing, or amplitude increasing) do not typically occur as a direct result of reflection.
