Q
Q: A wave has a frequency of 60 Hz and a wavelength of 3 m. What is its speed? (2016)
Solution:
Speed v = f × λ = 60 Hz × 3 m = 180 m/s.
Steps: 6
Show Steps
Step 1: Understand the formula for wave speed, which is Speed (v) = Frequency (f) × Wavelength (λ).
Step 2: Identify the frequency of the wave, which is given as 60 Hz.
Step 3: Identify the wavelength of the wave, which is given as 3 m.
Step 4: Plug the values into the formula: v = 60 Hz × 3 m.
Step 5: Calculate the speed: 60 × 3 = 180 m/s.
Step 6: Conclude that the speed of the wave is 180 m/s.
