Question

1. identify the correct equation used to calculate the speed of a wave:

a. $v = \frac{lambda}{t}$
b. $v = \frac{f}{lambda}$
c. $v = flambda$

Explanation:

Step1: Recall wave - speed formula

The speed \(v\) of a wave is related to its frequency \(f\) and wavelength \(\lambda\). The correct formula is \(v = f\lambda\), where \(f\) is the number of waves per second (frequency) and \(\lambda\) is the distance between two consecutive crests or troughs (wavelength).

Answer:

c. \(v = f\lambda\)
