What is a pulse wave?Choose a point value.Choose a point value.Click here for Final Jeopardy3Of transverse or longitudinal, light waves are this.A single handclap could be classified as this type of wave.This is the reciprocal of the period of a wave.This is the distance a travelling wave moves in one period.This is what happens when a wave encounters a boundary and bounces back.Of mechanical or nonmechanical, sound waves are this.This happens when the freqency of a force matches the natural frequency.This word refers to all sounds that are in the range of hearing.This is the resultant of two equal waves travelling in opposite directions.

Of aluminum and water, this would have a higher speed of sound. This is the lowest natural frequency of a given system.This sonic word means sounds with frequencies above 20,000 Hz, too high for humans to hear.Of inverted or upright, this describes a wave reflecting off a fixed boundary.This happens when two waves have equal displacements on opposite sides of the equilibrium position.This is a point on a standing wave that does not move from equilibrium.This causes a shift in the frequency of waves because of the relative motion of the source and observer. This is the second harmonic of a 440 Hz note.This sonic word refers to speeds faster than Mach 1.

This is the beat frequency when 340 Hz and 342 Hz sounds are heard simultaneously.A tube open only at one end will have only these harmonics.This refers to the lowest intensity of sound that can be hear by the average person.This is what happens to the loudness of a sound that increases 10dB.A standing wave in an air column in a tube open at both ends will have at least this many nodes. This is the approximate intensity of sounds at the threshold of pain level. What is 250 Hz?
