Question

identify the correct equation used to calculate the speed of a wave.
○ ( v = \frac{f}{lambda} )
○ ( v = flambda )
○ ( v = \frac{lambda}{f} )

Explanation:

To determine the correct equation for wave speed, we recall the relationship between wave speed (\(v\)), frequency (\(f\)), and wavelength (\(\lambda\)). The wave speed is the product of frequency and wavelength.

• The first option \(v = \frac{f}{\lambda}\) is incorrect as it suggests dividing frequency by wavelength.
• The second option \(v = f\lambda\) is correct because wave speed equals frequency multiplied by wavelength.
• The third option \(v = \frac{\lambda}{f}\) is incorrect as it divides wavelength by frequency.

Answer:

B. \( v = f\lambda \)
