What happens when a wave bounces back after it hits a boundary?
that depends on the boundary if it is a fixed or hard boundary, there is zero displacement and the reflected wave changes its polarity , i.e. it undergoes 180 deg phase change if it is a flexible or soft boundary, the restoring force is zero and the reflected wave has the same polarity in other words there is no change in phase
Reflection from a hard boundary produces what?
a 180 degree phase shift of the incident wave in the reflected wave.
When a wave reflects from a fixed boundary the only change in the wave is the direction of travel?
true
When a wave reflects from a fixed boundary the wave changes direction of travel and is slowed down True or false?
First statement: true Second statement: false
Is it possible to have a longitudinal wave in stretched string?
yes, Its possible to have a longitudinal wave on a stretched string by stroking it along its length by a rosined cloth. However, in the wave motion of a stretched string ( tant string with fixed ends) wave (disturbance) produced at one fixed end travels along the length of the string and get reflected back at the other end. Since the original wave and the reflected wave have the same frequency and amplitude, they superimpose to produce stationary transverse disturbance.

What happens when a wave on a rope strikes a free boundary?
Reflected but not inverted
Reflection from a hard boundary produces what?
a 180 degree phase shift of the incident wave in the reflected wave.
What is the scientific explanation for echos?
An echo is a sound wave that has reflected off a boundary
When a wave reflects from a fixed boundary is the only change in the wave is the direction of travel?
true
When a wave reflects from a fixed boundary the only change in the wave is the direction of travel?
true
What happens to a wave if it is reflected from a more rigid medium?
it becomes louder
What is the result of a reflected sound wave?
The result of a reflected sound wave is obviously an echo.

When a sound wave is reflected what do you hear?
When a sound wave is reflected, you hear an echo.
What happen when a waves strikes a boundary between two materials?
Usually part of the wave energy is reflected, and part of the wave energy passes through, possibly at a different angle (i.e., refraction may occur).
