Questions & Step-by-Step Solutions
A wave has a frequency of 50 Hz and a wavelength of 2 m. What is the speed of the wave? (2021)
Step 1: Understand the formula for wave speed, which is v = fλ, where v is the speed, f is the frequency, and λ (lambda) is the wavelength.
Step 2: Identify the values given in the question: frequency (f) is 50 Hz and wavelength (λ) is 2 m.
Step 3: Substitute the values into the formula: v = 50 Hz * 2 m.
Step 4: Calculate the result: 50 * 2 = 100.
Step 5: Conclude that the speed of the wave (v) is 100 m/s.
Wave Speed Calculation – The speed of a wave can be calculated using the formula v = fλ, where v is the speed, f is the frequency, and λ is the wavelength.
