Physics Chapter 19
The frequency of a certain wave is 10 hertz and its period is: 0.1 s, 10 s, or 100 s?
0.1 s
an object that completes 10 vibrations in 20 seconds has a frequency of
0.5 hertz
the frequency of the second hand on a clock is
1/60 hertz
a 101-MHz radio wave has vibrations per second of
101,000,000
an object that completes 20 vibrations in 10 seconds has a frequency of
2 hertz
water waves pass by a piece of work floating on the water that bobs up and down one complete cycle each second. The waves are 2 meters long. What is the speed of the wave?
2 m/s
the amplitude of a wave is 1 meter. the crest-to-trough distance of the wave is: 0.5 m, 1 m, or 2 m?
2 meters
radio waves travel at the speed of light, 300,000 km/s. The wavelength of a radio wave received at 100 megahertz is
3.0 m
what is the speed of a wave traveling a distance of 6 meters in one second?
6 m/s
a 60-vibration-per-second wave travels 30 m in 1 s. its frequency is
60 hertz and it travels at 30 m/s
the period of the second hand on a clock is
60 seconds
a standing wave is likely produced when
a wave reflects upon itself
both a transverse wave and a longitudinal wave have: amplitude, frequency, wavelength, speed, or all of the above?
all of the above
the doppler effect is characteristic of : water waves, sound waves, light waves, or all of the above?
all of the above
wave interference occurs for: sound waves, lightwaves, water waves, or all of the above?
all of the above
the vibrations of a longitudinal wave move
along the same direction of wave travel
some of a waves energy dissipates (is lost) as heat. in time, this will reduce the waves: amplitude, wavelength, or frequency?
amplitude
the vibrations of a transverse wave move
at right angles, (perpendicular), to the direction of wave travel.
a red shift for light indicates that the light source is moving
away from you
if you quickly run away from the orchestra at a concert, the frequency of the sound you hear will be increased or decreased?
decreased
a doppler effect occurs when a source of sound moves : towards you, away from you, or either?
either way
a shock wave is produced when a wave source moves
faster than the waves it produces
a sonic boom is produced by an airplane flying at a speed
greater than the speed of sound
if you double the frequency of a vibrating object, its period
halves
if you quickly run toward the orchestra at a concert, the frequency of the sound you will hear will be increased or decreased?
increased
the frequency of a simple pendulum does NOT depend on: its mass, its length, or the acceleration due to gravity?
its mass
a node is a position of
minimum amplitude
the distance traveled by a wave during a single period is
one wavelength
repeatedly dipping your fingers into water produces waves. increasing the frequency of dipping produces waves that are shorter or longer?
shorter
the pendulum with the greatest frequency is one with the shortest or longest length?
shortest
the source of all waves is something that vibrates, energy, or a force of some kind?
something that vibrates
is light, sound or a radio a longitudinal wave?
sound
an aircraft that flies faster than the speed of sound is said to be subsonic, supersonic, or impossible?
supersonic
a blue shift for light indicates that the light source is moving
toward you
all waves have in common a; pattern, vibrating source, or variable regions of high and low pressure?
vibrating source
a wiggle in time is a vibration or wave?
vibration
a wiggle in both space and time is a vibration or wave?
wave
