What is the frequency of a red laser beam, with a wavelength of 670 nm, which your astronomy instructor might use to point to slides during a lecture on galaxies?

The frequency of a red laser beam is .

Explanation:

It is given that,

Wavelength of red laser beam,

We need to find the frequency of red laser beam. It can be calculated as :

So, the frequency of a red laser beam is . Hence, this is the required solution.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
