How is a wave changed by reflection?
When a wave traversing in a medium of less refractive index gets reflected at a medium of greater refractive index then wave undergoes a phase change of pi radians. But if the same reflection takes place as the wave traverses from a medium of greater refractive index to that of less refractive index, then no such phase change. The later reflection is known as total internal reflection. So as light traversing in air gets reflected at glass then phase change of pi radians occurs.
Reflection from a hard boundary produces what?
a 180 degree phase shift of the incident wave in the reflected wave.
How do wave refraction and diffraction and reflection affect the behavior of waves?
Waves can and do meet boundaries in their medium. When a wave meets a boundary, it can be reflected or transmitted. Reflection can be partial or complete. Reflection can also involve a phase flip
What determines the direction of energy transfer in a phase change?
light is form of energy then light is reflected at boundary of rarer medium and denser medium reflected ray is phase change of 180 degree's energy is phase changed direction of energy is opposite of transfer ed way
What are the reflection refraction diffraction?
* Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering a medium at an angle will change direction. * Diffraction refers to the "bending of waves around an edge" of an object. Diffraction depends on the size of the object relative to the wavelength of the wave. * Reflection:Waves can and do meet boundaries in their medium. When a wave meets a boundary, it can be reflected or transmitted. Reflection can be partial or complete. Reflection can also involve a phase flip (change of phase of 180 degrees.) * All these phenomena apply to electromagnetic waves, such as light waves, as well as to pressure waves and water waves.

Why waves travelling on string always invert upon reflection?
Because the reflection is off of a point where the string is not allowed to move. You can determine the phase of a reflected wave relative to the incoming wave from the freedom of motion of the point of reflection. Since the point of reflection in the case of a string is not allowed to move, we can imagine that if it was a point on a longer string (and thus free to move) what would be the required phase of a wave coming from the distance moving in the direction of the reflected wave that does not move that point. Thus the reflected wave must always cancel the incoming wave at the point of reflection, the only phase that will fulfill this condition is the inversion (180 degree phase shift).

Why an exssecively thin film appears black in the reflection of light?
Destructive interference. If the sheet is very thin, near half the wavelength of the incident light then light reflected from the top layer is out of phase with light reflected from the bottom layer. These two reflected light waves will cancel each other out.

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
