longitudinalal waves
When an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still the result is a standing still wave.

standing wave!
The angle of approach and the reflected angle is always the same.
Standing waves are formed when the reflected wave reinforces the initial wave at a resonant frequency. At other frequencies, the reflected wave tends to cancel out the initial wave. One example of a standing wave is when a guitar string is plucked. Due to the tension of the string, the length, and the mass, the string will vibrate at one frequency.
Reflected
An object that appears black is absorbing all colors therefore none of the colors in the spectrum are being reflected.
A reflected duplication that appears identical but in reverse.
