Answer:
Speed = 10 m[tex]s^{-1}[/tex]
Explanation:
Given
wavelength = 5 m
frequency = 2 Hz = 2 [tex]s^{-1}[/tex]
Speed = ?
We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:
v = fλ
Hence, Speed = 2 [tex]s^{-1}[/tex] x 5 m
= 10 m[tex]s^{-1}[/tex]
