Question: What is the frequency of a wave if its wavelength is 2 meters and the speed of the wave is 340 m/s? (2020)

Options:

  1. 170 Hz
  2. 340 Hz
  3. 85 Hz
  4. 420 Hz

Correct Answer: 170 Hz

Exam Year: 2020

Solution: 

Frequency (f) can be calculated using the formula f = v/λ. Here, f = 340 m/s / 2 m = 170 Hz.

Questions & Step-by-Step Solutions

What is the frequency of a wave if its wavelength is 2 meters and the speed of the wave is 340 m/s? (2020)
  • Step 1: Identify the formula for frequency, which is f = v / λ.
  • Step 2: Determine the values you have: the speed of the wave (v) is 340 m/s and the wavelength (λ) is 2 m.
  • Step 3: Substitute the values into the formula: f = 340 m/s / 2 m.
  • Step 4: Perform the division: 340 divided by 2 equals 170.
  • Step 5: Conclude that the frequency of the wave is 170 Hz.
