a wave travels at a speed of 793 m/s and has a wavelength of 2.3 meters. calculate the frequency of the wave​
Savatey [412]

Answer:

344.8 Hz

Explanation:

The frequency of a wave is given by:

f=\frac{v}{\lambda}

where

v is the speed of the wave

\lambda is its wavelength

Here we have

v = 793 m/s

\lambda=2.3 m

Substituting into the equation, we find

f=\frac{793 m/s}{2.3 m}=344.8 Hz

Licemer1 [7]
You have to convert 400 cm into meters.
I'm assuming you mean a force of 10 Newtons in 8 seconds.
P= w/t
w=Fd
w= 10 x 4 = 40
P= 40 / 8 = 5
5 is your answer.
