I'll be happy to solve the problem using the information that
you gave in the question, but I have to tell you that this wave
is not infrared light.
If it was a wave of infrared, then its speed would be close
to 300,000,000 m/s, not 6 m/s, and its wavelength would be
less than 0.001 meter, not 12 meters.
For the wave you described . . .
Frequency = (speed) / (wavelength)
= (6 m/s) / (12 m)
= 0.5 / sec
= 0.5 Hz .
(If it were an infrared wave, then its frequency would be
greater than 300,000,000,000 Hz.)
Run electrity through or is postive to the circuit

Here's a explanation!
Let's solve your equation step-by-step.


Step 1: Multiply both sides by x.


(Divide both sides by 4).


Take the root.
ANSWER!

Hopefully, this helps you!!

Divide distance by the time it takes to travel that distance
the formula for time is divide distance/speed
