WAVES-PHYSICS QUESTIONS ANSWERSWITH SOLUTIONS 2024
Mechanical Waves - ANSWER waves that travel along a spring
Wave - ANSWER a vibratory (periodic) disturbance that is transmitted through a material or through
space
Transverse Wave - ANSWER particles of the medium exhibit SHM about a rest position perpendicular to
the direction of the motion of the wave
Longitudinal Wave - ANSWER a disturbance causes the particles of the material to vibrate in SHM in a
direction parallel to the direction of motion of the wave
Surface Wave - ANSWER motions of particles are both parallel and perpendicular to the direction of the
motion of the wave
Period - ANSWER the time it takes for the wave's motion to repeat itself
Frequency - ANSWER the number of times the motion repeats itself in a time interval of one unit of time
is known as the frequency of the wave. (Hz)
Hz - ANSWER cycles per second (or s^-1)
Period= - ANSWER 1/(frequency)
Amplitude - ANSWER the maximum displacement of any particle in the medium relative to its rest
position
Crest - ANSWER the maximum upward displacement
Trough - ANSWER the maximum downward displacement
, V= - ANSWER (frequency)(wavelength)
Power is relative to - ANSWER (frequency)^2
Same period= - ANSWER same length
Nodes - ANSWER the points that do not move (when two waves "combine")
Antinodes - ANSWER crest-trough combinations
Pulse - ANSWER a single vibratory disturbance (pulled and then released)
Reflection - ANSWER when a wave travels from one medium to another, part of the energy of the wave is
transmitted into the new medium with the same frequency, part is absorbed, and part moves back into
the original medium (or is reflected) with the same frequency
Interference - ANSWER two kinds-constructive and destructive, two or more waves result of two waves
passing simultaneously through the same area of a medium independently that affect the medium
independently but do not affect each other
Standing Waves - ANSWER a wave being continuously produced by an up-and-down motion on a string
traveling toward a barrier and the reflect wave emerging from it. (Incident and reflected waves have the
same frequencies and amplitudes but are traveling in opposite directions. This produces a wave that
appears to "stand still" in the horizontal direction.
Reflection - ANSWER after sending pulse, (sent right, comes back left)
Tighter Spring - ANSWER quicker, smaller waves (pulses)
Slower = - ANSWER low frequency
