Question: A wave travels along a string with a speed of 300 m/s and has a frequency of 150 Hz. What is the wavelength of the wave?

Options:

  1. 1.0 m
  2. 2.0 m
  3. 3.0 m
  4. 4.0 m

Correct Answer: 2.0 m

Solution: 

Wavelength λ is given by λ = v/f. Here, v = 300 m/s and f = 150 Hz. Thus, λ = 300/150 = 2.0 m.

Questions & Step-by-Step Solutions

A wave travels along a string with a speed of 300 m/s and has a frequency of 150 Hz. What is the wavelength of the wave?
  • Step 1: Identify the speed of the wave (v). In this case, v = 300 m/s.
  • Step 2: Identify the frequency of the wave (f). Here, f = 150 Hz.
  • Step 3: Use the formula for wavelength (λ), which is λ = v / f.
  • Step 4: Substitute the values into the formula: λ = 300 m/s / 150 Hz.
  • Step 5: Calculate the result: λ = 2.0 m.
  • Wave Properties – Understanding the relationship between wave speed, frequency, and wavelength.
  • Formula Application – Applying the formula λ = v/f correctly to find the wavelength.
