Wavelength of the wave if its frequency is 12.0 hertz and its speed is 1.2 meters per second?

0.1m

Explanation:

Given parameters:

Frequency  = 12hz

Speed  = 1.2m/s

Unknown:

Wavelength of the wave  = ?

Solution:

The wavelength of the wave can be derived using the expression below;

      V  = f∧

V is the speed of the wave

f is the frequency of the wave

∧ is the wavelength

 So;

         ∧  =

Now, insert the parameters and solve;

       ∧   =   = 0.1m

c) up is the direction the magnetic force is acting on the charge.
