Questions & Step-by-Step Solutions

A wave has a frequency of 60 Hz and a wavelength of 1.5 m. What is its speed? (2022)
  • Step 1: Identify the formula for wave speed, which is Speed (v) = frequency (f) × wavelength (λ).
  • Step 2: Write down the given values: frequency (f) = 60 Hz and wavelength (λ) = 1.5 m.
  • Step 3: Substitute the values into the formula: v = 60 Hz × 1.5 m.
  • Step 4: Calculate the result: 60 × 1.5 = 90.
  • Step 5: Write the final answer: The speed of the wave is 90 m/s.
  • Wave Speed Calculation – The speed of a wave can be calculated using the formula v = f × λ, where v is speed, f is frequency, and λ is wavelength.
