# Waves - Physics

 Period Equation? T = 1/f Speed of a wave? v = f λ What is phase reversial? The reflected pulse is said to be inverted, out of phase, or 180° outof phase with the incident pulse. It is said to have undergone a phase reversal. What is constructive interference? The type of resulting wavedepends on whether the pulses were produced on the same side or on opposite sides of thespring. However, once they have passed they continue as though they had not met.If they are produced on the same side of the springconstructive interference occurs, producing a super crest. What is destructive interference? If they are producedon opposite sides of the spring destructive interference occurs, producing a smaller wave,or no wave at all at that instant. How is a standing wave created? If a series of waves are created from each end of a spring of the same amplitude andfrequency, a stationary wave or standing wave is created. What is reflection? Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. What is refraction? This change in direction of the waves as theygo from one medium to another is called refraction. What is diffraction? This bending of waves as they pass through a slit is called diffraction. What is coherent? Where waves are in-phase. How does one achieve coherent? Have two sets of circular radiating waves that are in phase and of the same amplitude. ﻿﻿ AuthorAnonymous ID88377 Card SetWaves - Physics DescriptionWave motion, Light motion Updated2011-05-30T12:06:14Z Show Answers
