Question: A sound wave travels through water at a speed of 1500 m/s. If the frequency of the sound wave is 300 Hz, what is the wavelength?

Options:

  1. 2 m
  2. 3 m
  3. 4 m
  4. 5 m

Correct Answer: 2 m

Solution: 

Wavelength λ = v/f = 1500 m/s / 300 Hz = 5 m.

Questions & Step-by-Step Solutions

A sound wave travels through water at a speed of 1500 m/s. If the frequency of the sound wave is 300 Hz, what is the wavelength?
  • Step 1: Identify the speed of the sound wave in water, which is given as 1500 m/s.
  • Step 2: Identify the frequency of the sound wave, which is given as 300 Hz.
  • Step 3: Use the formula for wavelength, which is Wavelength (λ) = Speed (v) / Frequency (f).
  • Step 4: Substitute the values into the formula: λ = 1500 m/s / 300 Hz.
  • Step 5: Perform the division: 1500 divided by 300 equals 5.
  • Step 6: Conclude that the wavelength of the sound wave is 5 meters.
  • Wave Properties – Understanding the relationship between speed, frequency, and wavelength of a wave.
  • Formula Application – Applying the formula for wavelength (λ = v/f) correctly to solve problems involving waves.
