Part of the energy carried by the sound bounces back from the wall, and is
perceived as an echo if you're far enough from the wall.
The rest of the energy enters the wall. Part of that is absorbed by the
material of the wall, and the rest emerges from the other side, where
it may be noticeable to people on that side of the wall, especially in a
cheap motel.
It can bounce off, be absorbed or can pass through
1. Wave may be completely reflected back. 2. Wave may penetrate and go through the boundary. 3. Wave can be completely cancelled.

Some Will bounce, some will be absorbed.
It refracts, reflects, and absorbs light.

Three things can happen 1. Absorb the light, like black clothing 2. Bounce off the surface, like a mirror 3. Nearly all the light can go through, like a window
This happens if the light makes a 90 degree angle with the boundary (hits is straight on), so it just keeps going in a straight line.
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

a sixer is when the batsman hits a shot without touching the boundary.
Three things can happen 1. Absorb the light, like black clothing 2. Bounce off the surface, like a mirror 3. Nearly all the light can go through, like a window
it can be transmitted, reflected, refracted or diffused. In most cases, some combination of these occurs.
This happens if the light makes a 90 degree angle with the boundary (hits is straight on), so it just keeps going in a straight line.

If it hits the umpire behind home plate, it is a foul ball. If it hits a field umpire who is in bounds, then it is a live ball, meaning that the batter might be thrown out at first, or he might reach first base safely (and then this would be scored as a hit without an error),
Lunar eclipses always happen at the full moon phase. A lunar eclipse happens when the Moon is DIRECTLY lined up with the Sun and the Earth, so precisely that the Earth's shadow hits the Moon.
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
