Question

A wave pulse travels from a more dense medium into a less dense medium. What happens to the reflected wave?
Group of answer choices

the reflected wave is upright

the reflected wave moves sideways

the reflected wave is inverted

the reflected wave moves 30 degrees

Answer 1

When a wave pulse travels from a more dense medium to a less dense medium, the reflected wave is inverted. This means that if the incident wave is a peak, the reflected wave will be a trough, and vice versa.

So, the correct answer is: **the reflected wave is inverted.**
