Practice Exam
| Question | Answer |
|---|---|
| You swing to and fro on a playground swing. If you stand rather than sit, the time for a to-and-fro swing: | shortened |
| The time it takes for a pendulum swinging to and fro refers to its | period |
| The period of a 10-Hz wave is | 1/10s |
| A wave transfers | energy |
| Find the speed of a wave by multiplying its frequency by its | wavelength |
| The vibrations in a transverse wave move in a direction | perpendicular to the wave |
| The vibrations in a longitudinal wave move in a direction | along and parallel to the wave |
| Interference is a characteristic of | all waves |
| Standing waves are the result of | waves reflecting upon themselves |
| The Doppler effect occurs when a source of sound moves | towards you or away from you |
| Compared with the sound you hear from the siren of a stationary fire engine, its sound when it approaches you has an increased | frequency |
| Bow waves are produced by waves of water | overlapping one another, constructively interfering, and moving slower than the source producing them |
| Shock waves are produced by waves of sound | overlapping one another, constructively interfering, and moving slower than the source producing them |
| During the time an aircraft produces a sonic boom, the aircraft is | flying faster than sound |
| The sound waves that most humans cannot hear are | infrasonic AND ultrasonic |
| Sound travels in air by a series of | compression and rarefactions |
| The compression and rarefactions in sound normally travel | in the same direction |
| Sound travels in | solids, liquids, and gases |
| The speed of sound is slightly greater on a | hot day |
| Sound will travel fastest in | a steel beam |
| The loudness of sound is most closely related to its | amplitude |
| Your friend states that under all conditions, any radio wave travels faster than any sound wave. You | agree with your friend |
| When you tap a piece of wood it will produce a characteristic sound related to its | natural frequency |
| When an object is set vibrating by a wave that has a matching frequency, what occurs is | resonance |
| Noise-cancelling devices make use of sound | interference |
| The phenomenon of beats is the result of sound | interference |
| A 1134-Hz tuning fork is sounded at the same time a piano note is struck. You hear 3 beats per second. The frequency of the piano strings is | More information needed |
| The pitch of a sound is most closely related to its | frequency |
| Compared with a sound 60 decibels, a sound of 80 decibels has an intensity | 100 times greater |
| Compared with a fundamental tone, the frequency of its second harmonic is | twice as much |
| Which of these does not belong in the family of electromagnetic waves? | sound |
| Light that is not transmitted by opaque materials is | converted to internal energy in the material |
| When the shadow of the moon falls on Earth, we have a | solar eclipse |
| Black is the combination of | none of these |
| To say that a rose petal is red is to say that it | reflects red |
| The color of light most intense in the solar radiation curve is | yellow-green |
| When red and blue light are overlapped, the color produced is | magenta |
| The complementary color of blue is | yellow |
| The blueness of the daytime sky is due mostly to light | scattering |
| The redness of a sunrise or sunset is due mostly to light that hasn't been | scattered |
| The greenish blue of ocean water mostly involves light that is | absorbed |
| Your distance of your image behind a plane mirror is equal to | your distance in front of the mirror |
| Refraction occurs when a wave crosses a boundary and changes | speed and direction |
| When white light passes through a prism, the light that bends more than green is | blue |
| A rainbow is the result of light in raindrops that undergoes | internal reflection, dispersion, and refraction |
| When a diver points a flashlight upward toward the surface of the water at an angle 20 degrees from the normal, the beam of light | passes into the air above |
| A real image can be cast on a screen by | converging lens |
| Huygens' principle for light is primarily described by | waves |
| A diffraction grating relies on light | interference |
| When light undergoes interference, it can sometimes | cancel completely |
| Colors in a soap bubble result from light | subtracted from incident light |
| Polarization is a property of | transverse waves |
| A hologram best illustrates | diffraction |
| In the proportion E ` f, the f stands for the | frequency of light |
| The energy of an emitted photon is related to its | frequency |
| Among these colors, the one having the most energy per photon is | violet |
| The red glow in the neon tube of an advertising sign is a result of | excitation |
| All parts of a laser beam have the same | frequency, speed, and phase |
| The model of light supported by the photoelectric effect is the | particle model |
| Planck's constant can be found by dividing the energy of a photon by its | frequency |
