Questions & Step-by-Step Solutions
A wave traveling along a string has a frequency of 50 Hz and a wavelength of 2 m. What is the speed of the wave? (2020)
Step 1: Identify the frequency of the wave, which is given as 50 Hz.
Step 2: Identify the wavelength of the wave, which is given as 2 m.
Step 3: Use the formula for wave speed, which is Speed (v) = frequency (f) × wavelength (λ).
Step 4: Substitute the values into the formula: v = 50 Hz × 2 m.
Step 5: Calculate the result: 50 × 2 = 100.
Step 6: State the speed of the wave, which is 100 m/s.
Wave Speed Calculation – The speed of a wave can be calculated using the formula v = f × λ, where v is the speed, f is the frequency, and λ is the wavelength.
