Question

What is the speed of a wave with a frequency of 2 Hertz and a wavelength of 87 m?

0.023 m/s
43.5 m/s
89 m/s
174 m/s
​

Answer 1

The answer to your problem is, D. 174 m/s

Step-by-step explanation:

Formula:

wave speed = frequency * wavelength

Speed of wave = 2Hz × 87m ( Look at question for the numbers )

Speed of wave = 174m/s

Simple math..

Thus the answer to your problem is, 174m/s
