Answer:
Velocity of wave = 45 m[tex]s^{-1}[/tex]
Explanation:
Given
wavelength = 3 m
Frequency = 15 Hz = 15 [tex]s^{-1}[/tex]
Velocity = ?
We know that for all waves, the relationship between wavelength λ, frequency f and velocity v is same and given by the equation:
v = fλ
Hence, Velocity of wave = 15 [tex]s^{-1}[/tex] x 3 m
= 45 m[tex]s^{-1}[/tex]
