Answer 1

Answer:

180000 m/s

Explanation:

Velocity = Wavelength x Frequency

If Wavelength = 1.2 and Frequency = 150000

Then velocity = 1.2 * 150,000 Which equals 180000

Answer 2

Answer:

Solution given:

frequency[f]=150000Hz

velocity[V]=x

wave length=1.2m

we have

wave length=$\frac{V}{f}$

1.2m=$\frac{x}{150000}$

1.2×150000=$\frac{x}{1}$

x=18000m/s

velocity=180000m/s
