Question: What is the frequency of a wave with a speed of 300 m/s and a wavelength of 3 m? (2023)

Options:

  1. 100 Hz
  2. 150 Hz
  3. 200 Hz
  4. 250 Hz

Correct Answer: 150 Hz

Exam Year: 2023

Solution: 

Frequency (f) = speed (v) / wavelength (λ) = 300 m/s / 3 m = 100 Hz.

Questions & Step-by-Step Solutions

What is the frequency of a wave with a speed of 300 m/s and a wavelength of 3 m? (2023)
  • Step 1: Identify the formula for frequency, which is f = v / λ.
  • Step 2: Write down the values given in the question: speed (v) = 300 m/s and wavelength (λ) = 3 m.
  • Step 3: Substitute the values into the formula: f = 300 m/s / 3 m.
  • Step 4: Perform the division: 300 divided by 3 equals 100.
  • Step 5: Conclude that the frequency (f) is 100 Hz.
