Answer:
your question answer is 22°
Answer:
they're important because they simplify the results of the comparison
First of all, we can calculate the frequency of the photon, which is related to the wavelength by the following equation:
where c is the speed of light and
is the photon wavelength. Substituting into the formula, we find the frequency
Now we can find the energy of the photon with the following equation:
where h is the Planck constant. Substituting numbers, we find
Direction.
And value that is not scalar has both magnitude and direction; such as 3.5 m/s (magnitude) East (Direction).
A battery powering a flashlight is the correct answer
