Question

What is the speed of a wave whose wavelength is 30 m and frequency is 20 Hz? Show your work​

Answer 1

Answer:

frequency = speed/ wavelength

speed = wavelength × frequency

speed = 30 × 20

speed = 600mhz

Answer 2

Answer:

600 m/s

Explanation:

Data :

   Frequency = f = 20 hz

   Wavelenght =  λ = 30 m

Formula for wave speed

        V = fλ = 20 × 30 = 600 m/s
