Question: A wave travels with a speed of 340 m/s and has a frequency of 170 Hz. What is its wavelength? (2022)

Options:

  1. 2.0 m
  2. 1.0 m
  3. 0.5 m
  4. 3.0 m

Correct Answer: 2.0 m

Solution: 

Wavelength λ = v/f = 340 m/s / 170 Hz = 2.0 m.

Questions & Step-by-Step Solutions

A wave travels with a speed of 340 m/s and has a frequency of 170 Hz. What is its wavelength? (2022)
  • Step 1: Identify the speed of the wave (v). In this case, it is 340 m/s.
  • Step 2: Identify the frequency of the wave (f). In this case, it is 170 Hz.
  • Step 3: Use the formula for wavelength (λ), which is λ = v / f.
  • Step 4: Substitute the values into the formula: λ = 340 m/s / 170 Hz.
  • Step 5: Perform the division: 340 divided by 170 equals 2.0.
  • Step 6: Conclude that the wavelength (λ) is 2.0 meters.
  • Wave Properties – Understanding the relationship between wave speed, frequency, and wavelength, which is described by the formula λ = v/f.
