Question

If the speed of a wave is 150 m/s and it’s frequency is 2 Hz , what is its wavelength ?

Answer 1

Wave equation :
Velocity = (Wavelength) X (Frequency)
Wavelength = (Velocity) / (Frequency)
= (150)/(2)
= 75m

OR


This may help :
Frequency = 1 / Time(period)
Wave length = Displacement
Velocity of wave = Velocity.

To find Distance, we know from kinematics
Displacement= (Velocity) X (Time)
= (Velocity) X (1/Frequency)
= (150) X (1/2)
= 75m

Answer 2

75 m

Step-by-step explanation:

wavelength = frequency/ speed = 75 m
