Question: A wave has a speed of 300 m/s and a frequency of 150 Hz. What is its wavelength? (2022)

Options:

  1. 1 m
  2. 2 m
  3. 3 m
  4. 4 m

Correct Answer: 2 m

Exam Year: 2022

Solution: 

Wavelength λ can be calculated using the formula λ = v/f. Therefore, λ = 300 m/s / 150 Hz = 2 m.

Questions & Step-by-Step Solutions

A wave has a speed of 300 m/s and a frequency of 150 Hz. What is its wavelength? (2022)
  • Step 1: Identify the given values. The speed of the wave (v) is 300 m/s and the frequency (f) is 150 Hz.
  • Step 2: Write down the formula for wavelength (λ), which is λ = v / f.
  • Step 3: Substitute the values into the formula. Replace v with 300 m/s and f with 150 Hz.
  • Step 4: Perform the division: 300 m/s divided by 150 Hz equals 2 m.
  • Step 5: Conclude that the wavelength (λ) is 2 meters.
  • Wave Properties – Understanding the relationship between wave speed, frequency, and wavelength.
  • Formula Application – Applying the formula λ = v/f to calculate wavelength from given speed and frequency.
