What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m? What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

a) What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m?

5m/s

b) What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

40Hz

Explanation:

a) What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m?

Wave speed(v) = Frequency(f) × Wavelength (λ)

= 50Hz × 0.10m

=5m/s

b) What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

The formula for Frequency when given wave speed and wave length = Wave speed/ wave length

f = v/λ

Frequency = 20m/s ÷ 0.50m

Frequency = 40Hz

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
