Questions & Step-by-Step Solutions

A wave travels at a speed of 300 m/s and has a frequency of 150 Hz. What is its wavelength?
  • 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 wave speed, which is v = f * λ, where λ is the wavelength.
  • Step 4: Rearrange the formula to solve for wavelength (λ). This gives us λ = v / f.
  • Step 5: Substitute the values into the formula: λ = 300 m/s / 150 Hz.
  • Step 6: Perform the division: 300 divided by 150 equals 2.
  • Step 7: Conclude that the wavelength (λ) is 2 meters.
  • Wave Properties – Understanding the relationship between speed, frequency, and wavelength of a wave.
  • Formula Application – Applying the formula v = fλ to solve for wavelength.
