Question

A wave frequency is 4 hz and. Its wavelength is 4 m. What is wave speed

Answer 1

Answer:

HERE C= VELOCITY OR SPEED OF LIGT

Answer 2

Answer:

solution

given by frequency =4hz

wavelength (lemda) = 4m

we know that the speed = distance/ time

so wave speed = wavelength /Time

and frequency = 1/Time

wave speed = wavelength× frequency

wave speed = 4×4 = 16 m/s
