Question

The frequency of a wave is 500 Hz and its wavelength is 0.66 m. What is the speed of the wave?

• A. 132 m/s
• B. 330 m/s
• C. 660 m/s
• D. 100 m/s

Hint:

Wave speed \(v\) is always the product of frequency \(f\) and wavelength \(\lambda\): \[ v = f \times \lambda \] Ensure units are consistent.

Answer 1

The Correct Option is B

Step 1: Write down the known values 
Frequency, \( f = 500\, \text{Hz} \) 
Wavelength, \( \lambda = 0.66\, \text{m} \) 
Step 2: Recall the formula for wave speed 
\[ v = f \times \lambda \] 
Step 3: Substitute the values 
\[ v = 500 \times 0.66 = 330 \, \text{m/s} \] 
Step 4: Conclusion 
The speed of the wave is \(330\, \text{m/s}\).
