What is the speed of a wave wit a wavelength of 3.0 m and a period of 0.40s

Question

Need help help with problem really having a lot of trouble hope everyone has an Blessed day

Answer 1

The formula you need for this is

v = f λ

(velocity = frequency • wavelength)

A built-in reminder for this relationship is the units:

meters / second = meters • 1/seconds (aka hz, frequency)

therefore v = 3m / 0.4 seconds = 7.5 m/s
