A wave generator produces straight, parallel wave fronts in a shallow tank of uniform-depth water. As the frequency of vibration of the generator increases, which characteristic of the wave will always decrease? (1) amplitude (3) wavelength (2) phase (4) speed

Reason

1. A student claps his hands once to produce a sudden loud sound that travels through the air. This sound is classified as a (1) longitudinal mechanical wave (2) longitudinal electromagnetic wave (3) transverse mechanical wave (4) transverse electromagnetic wave

Reason

1. A student generates water waves in a pool of water. In order to increase the energy carried by the waves, the student should generate waves with a (1) greater amplitude (2) higher frequency (3) greater wavelength (4) longer period

Reason

1. A sound wave produced by a loudspeaker can travel through water, but not through a vacuum. In comparison, a red light wave produced by a laser can travel through (1) water, but not through a vacuum (2) a vacuum, but not through water (3) both water and a vacuum (4) neither water nor a vacuum

Reason

Reason

Reason

1. Which statement correctly describes one characteristic of a sound wave?
2. A sound wave can travel through a vacuum
3. A sound wave is a transverse wave
4. The amount of energy a sound wave transmits is directly related to the wave’s amplitude.
5. The amount of energy a sound wave transmits is inversely related to the wave’s frequency

Reason

1. A ringing bell is located in a chamber. When the air is removed from the chamber, why can the bell be seen vibrating but not be heard?
2. Light waves can travel through a vacuum, but sound waves cannot.
3. Sound waves have greater amplitude than light waves.
4. Light waves travel slower than sound waves.
5. Sound waves have higher frequencies than light waves.

Reason

1. A pulse traveled the length of a stretched spring. The pulse transferred
2. Energy, only 2. Mass, only
3. Both energy and mass 4. Neither energy nor mass

Reason

1. As a transverse wave travels through a medium, the individual particles of the medium move
2. Perpendicular to the direction of wave travel
3. parallel to the direction of wave travel
4. in circles 4. in ellipses

Reason

1. The amplitude of a sound wave is most closely related to the sound’s
2. 1. speed 2. wavelength
3. 3. loudness 4. Pitch

Reason

1. Transverse waves are to radio waves as longitudinal waves are to
2. 1. light waves microwaves
3. ultraviolet waves 4. sound waves

Reason

1. A space probe produces a radio signal pulse. If the pulse reaches Earth 12.3 seconds after it is emitted by the probe, what is the distance from the probe to Earth? The speed of light c= 3.0 X 108 m/s
