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

1. QuestionMultiple choice

What is the relationship among wave speed, frequency, and wavelength?

Please select an answer first.

Correct answer: A

The correct answer is v=fλv=f\lambda.

  1. Identify the wave model: Determine the medium, wave type, frequency, wavelength, amplitude, and direction described in the question.
  2. Apply the wave relationship: Wave speed equals frequency multiplied by wavelength, so changing either quantity changes the relationship when the medium permits it.
  3. Check units and physical meaning: The correct answer is v=fλv=f\lambda.

Wave speed equals frequency multiplied by wavelength, so changing either quantity changes the relationship when the medium permits it.
