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

Question

Group of answer choices

the reflected wave is inverted

the reflected wave moves 30 degrees

the reflected wave moves sideways

the reflected wave is upright

Answer 1

When a wave pulse travels from a less dense medium (like air) into a more dense medium (like water), the reflected wave will be inverted. This means that if the incident wave is traveling upward, the reflected wave will travel downward (and vice versa).

So, the correct answer is:

the reflected wave is inverted
