Question: A wave travels with a speed of 300 m/s and has a frequency of 150 Hz. What is the wavelength? (2020)

Options:

  1. 2 m
  2. 1.5 m
  3. 3 m
  4. 0.5 m

Correct Answer: 2 m

Exam Year: 2020

Solution: 

Wavelength (λ) = Speed (v) / Frequency (f) = 300 m/s / 150 Hz = 2 m.

Questions & Step-by-Step Solutions

A wave travels with a speed of 300 m/s and has a frequency of 150 Hz. What is the wavelength? (2020)
  • Step 1: Identify the speed of the wave, which is given as 300 m/s.
  • Step 2: Identify the frequency of the wave, which is given as 150 Hz.
  • Step 3: Use the formula for wavelength, which is Wavelength (λ) = Speed (v) / Frequency (f).
  • Step 4: Substitute the values into the formula: λ = 300 m/s / 150 Hz.
  • Step 5: Perform the division: 300 divided by 150 equals 2.
  • Step 6: 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 λ = v / f to calculate wavelength.
