Questions & Step-by-Step Solutions
A wave has a frequency of 500 Hz and a wavelength of 0.5 m. What is the speed of the wave? (2023)
Step 1: Identify the formula to calculate the speed of a wave, which is v = fλ.
Step 2: Understand that 'v' is the speed of the wave, 'f' is the frequency, and 'λ' (lambda) is the wavelength.
Step 3: Substitute the given values into the formula. Here, f = 500 Hz and λ = 0.5 m.
Step 4: Calculate the speed by multiplying the frequency (500 Hz) by the wavelength (0.5 m).
Step 5: Perform the multiplication: 500 * 0.5 = 250.
Step 6: Conclude that the speed of the wave is 250 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.
