If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave?

A1,285 m/s

B1,200 m/s
C1,800 m/s
D1,500 m/s

Verified Answer :

D.1500m/s

Speed= Distance/Time

: .You simply divide 9metres (distance) by 0.006 (time)

Answer

D. 1,500 m/s

Explanation

the wave equation states that,

V = λf

Where V ⇒ Velocity

λ ⇒ wavelength

f ⇒ Frequency

F = 1/T

Where T ⇒ period

F = 1/0.006

= 166.667

∴ V = 9 × 166.667

= 1,500 m/s
