Copy of Physics - Chapter 13 - Waves and their Properties

Do water waves push water from one place to another? Explain.

• A. No, water waves transfer only energy from one place to another.
• B. Yes, water waves transfer water from one place to another.

With reference to waves, what is a trough?

• A. the lowermost position of a wave
• B. the uppermost position of a wave
• C. the final position of a wave
• D. the initial position of the wave

Give an example of longitudinal waves.

• A. light waves
• B. water waves in a lake
• C. sound waves in air
• D. seismic waves in Earth’s surface

What does the speed of a mechanical wave depend on?

• A. the properties of the material through which it travels
• B. the shape of the material through which it travels
• C. the size of the material through which it travels
• D. the color of the material through which it travels

Which characteristic of a transverse wave is measured along the direction of propagation?

• A. The amplitude of a transverse wave is measured along the direction of propagation.
• B. The amplitude and the wavelength of a transverse wave are measured along the direction of propagation.
• C. The wavelength of a transverse wave is measured along the direction of propagation.
• D. The displacement of the particles of the medium in a transverse wave is measured along the direction of propagation.

Which kind of seismic waves cannot travel through liquid?

• A. compressional waves
• B. P-waves
• C. longitudinal waves
• D. S-waves

What is the period of a wave?

• A. the time that a wave takes to complete a half cycle
• B. the time that a wave takes to complete one cycle
• C. the time that a wave takes to complete two cycles
• D. the time that a wave takes to complete four cycles

When the period of a wave increases, what happens to its frequency?

• A. Its frequency decreases.
• B. Its frequency increases.
• C. Its frequency remains the same.

Is this statement true or false? The amplitudes of waves add up only if they are propagating in the same line.

• A. True
• B. False

Why is sound from a stereo louder in one part of the room and softer in another?

• A. Sound is louder in parts of the room where the density is greatest. Sound is softer in parts of the room where density is smallest.
• B. Sound is louder in parts of the room where the density is smallest. Sound is softer in parts of the room where density is greatest.
• C. Sound is louder in parts of the room where constructive interference occurs and softer in parts where destructive interference occurs.
• D. Sound is louder in parts of the room where destructive interference occurs and softer in parts where constructive interference occurs.
