PHYSICS TEST QUESTIONS EXAM ACCURATELY
SOLVED
are longitudinal waves - CORRECT ANSWER✅✅✅Sound waves
rarefaction - CORRECT ANSWER✅✅✅The trough of the sine curve used to represent a
sound wave corresponds to a
compression - CORRECT ANSWER✅✅✅Which of the following is the region of a sound
wave in which the density and pressure are greater than normal?
pitch - CORRECT ANSWER✅✅✅The highness or lowness of a sound is perceived as
frequency - CORRECT ANSWER✅✅✅Pitch depends on the ________ of a sound wave
solids than through gases - CORRECT ANSWER✅✅✅In general, sound travels faster
through
plane waves - CORRECT ANSWER✅✅✅At a large distance from a sound source, spherical
wave fronts are viewed as
compression - CORRECT ANSWER✅✅✅The point at which a ray crosses a wave front
corresponds to a ________ of a sound wave
one wavelength - CORRECT ANSWER✅✅✅The distance between wave fronts of plane
waves corresponds to _____ of a sound wave
higher in pitch than - CORRECT ANSWER✅✅✅A train moves down the track toward an
observer. The sound from the train, as heard by the observer, is _______ the sound heard by a
passenger on the train.
, all waves - CORRECT ANSWER✅✅✅The Doppler Effect occurs with
the pitch will not change - CORRECT ANSWER✅✅✅If you are on a train, how will the
pitch of the train's whistle sound to you as the train moves?
an area perpendicular to the direction of propogation - CORRECT ANSWER✅✅✅The
property of sound called intensity is proportional to the rate at which energy flows through
one-ninth - CORRECT ANSWER✅✅✅At a distance of 3 m, the intensity of a sound will be
________ the intensity it was at a distance of 1 m.
power - CORRECT ANSWER✅✅✅the intensity of a sound at any distance from the source
is directly proportional to the sound's
decibels - CORRECT ANSWER✅✅✅the perceived loudness of a sound is measured in
is approximately logarithmic - CORRECT ANSWER✅✅✅a sound twice the intensity of the
faintest audible sound is not perceived as twice as loud because the sensation of loudness in
human hearing
resonance - CORRECT ANSWER✅✅✅When the frequency of a force applied to a system
matches the natural frequency of vibration of the system, _______ occurs.
a standing wave - CORRECT ANSWER✅✅✅The Tacoma Narrows Bridge collapsed in
1940 when winds caused _______ to build up in the bridge.
all harmonic are present - CORRECT ANSWER✅✅✅When an air column vibrates in a pipe
that is open at both ends,
