Question

A water wave has a frequency of 2 Hertz and a wavelength of 5 cm. Calculate it speed

Answer 1

Answer: 0.1 m/s

Step-by-step explanation:

Use formula,

v = f * w where, v is speed, f is frequency and w is wavelength.

Now,

v = 2 * 5 * 10 ^ -2 ( Remember to convert all the units to SI units. Here 5 cm becomes 5 * 10 ^ -2 m. )

v = 0.1 m/s.
