Waves and Sound Practice Tests

These Grade 11 Science practice tests examine wave properties, frequency, wavelength, amplitude, sound, resonance, the Doppler effect, interference, standing waves, electromagnetic waves, and experimental analysis.

Skills covered

  • Using \(v=f\lambda\) and \(T=1/f\) to connect wave speed, frequency, wavelength, and period
  • Explaining sound pitch, loudness, intensity, echoes, resonance, and the Doppler effect
  • Analyzing reflection, refraction, diffraction, interference, polarization, nodes, antinodes, and harmonics
  • Distinguishing mechanical and electromagnetic waves and applying boundary conditions
  • Interpreting wave experiments, graphs, repeated trials, uncertainty, and systematic error

How to use these practice tests

Identify the wave type and medium first. Write the relevant relationship, keep units consistent, and connect the mathematical result to the physical behavior of the wave.

1. QuestionMultiple choice

Why can sound not travel through empty space?

Please select an answer first.

Correct answer: A

The correct answer is Sound is a mechanical wave that needs particles in a medium.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Sound requires interactions between particles, so a vacuum cannot transmit the pressure disturbances of sound.
  3. Check units and physical meaning: The correct answer is Sound is a mechanical wave that needs particles in a medium.

Sound requires interactions between particles, so a vacuum cannot transmit the pressure disturbances of sound.

2. QuestionMultiple choice

What property of sound is most closely related to perceived pitch?

Please select an answer first.

Correct answer: B

The correct answer is Frequency.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Higher frequency is perceived as higher pitch, while amplitude is more closely related to loudness.
  3. Check units and physical meaning: The correct answer is Frequency.

Higher frequency is perceived as higher pitch, while amplitude is more closely related to loudness.

3. QuestionMultiple choice

What property of sound is most closely related to perceived loudness?

Please select an answer first.

Correct answer: C

The correct answer is Amplitude or intensity.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Larger pressure variation generally means greater intensity and a louder perceived sound, subject to hearing response.
  3. Check units and physical meaning: The correct answer is Amplitude or intensity.

Larger pressure variation generally means greater intensity and a louder perceived sound, subject to hearing response.

4. QuestionMultiple choice

What causes resonance?

Please select an answer first.

Correct answer: D

The correct answer is A driving frequency matches or is close to a natural frequency.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Resonance produces a large response when periodic driving is near a system's natural frequency.
  3. Check units and physical meaning: The correct answer is A driving frequency matches or is close to a natural frequency.

Resonance produces a large response when periodic driving is near a system's natural frequency.

5. QuestionMultiple choice

A sound wave travels at 340 m/s340\,\text{m/s} with frequency 170 Hz170\,\text{Hz}. What is its wavelength?

Please select an answer first.

Correct answer: A

The correct answer is 2.0 m2.0\,\text{m}.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Using (\lambda=v/f), the wavelength is (340/170=2.0\,\text{m}).
  3. Check units and physical meaning: The correct answer is 2.0 m2.0\,\text{m}.

Using (\lambda=v/f), the wavelength is (340/170=2.0\,\text{m}).

6. QuestionMultiple choice

What is the Doppler effect?

Please select an answer first.

Correct answer: B

The correct answer is A perceived frequency change caused by relative motion of source and observer.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Relative motion changes the rate at which wave crests reach the observer, producing an observed frequency shift.
  3. Check units and physical meaning: The correct answer is A perceived frequency change caused by relative motion of source and observer.

Relative motion changes the rate at which wave crests reach the observer, producing an observed frequency shift.

7. QuestionMultiple choice

Why does a passing siren usually sound higher before it passes and lower afterward?

Please select an answer first.

Correct answer: C

The correct answer is The approaching source sends wavefronts closer together, then the receding source sends them farther apart.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Approach compresses arriving wavefront spacing and increases observed frequency; recession increases spacing and lowers it.
  3. Check units and physical meaning: The correct answer is The approaching source sends wavefronts closer together, then the receding source sends them farther apart.

Approach compresses arriving wavefront spacing and increases observed frequency; recession increases spacing and lowers it.

8. QuestionMultiple choice

What does sound intensity measure?

Correct answer: D

The correct answer is Power transmitted per unit area.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.

Correct answer: A

The correct answer is A logarithmic level related to sound intensity or pressure.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
