Which of the following sources of electromagnetic radiation will have the highest energy?

Which of the following sources of electromagnetic radiation will have the highest energy? Alright. So energy. Remember, energy is inversely proportional to wavelength. So highest energy correlates to the lowest or in this case, shortest wavelength. So looking for which one of these is the smallest in terms of their wavelengths. And remember, we know these are all wavelengths because wavelength is done in meters. Nanometers, centimeters, meters, and micrometers. They're all still meters at the end of the day. Now to be able to compare them, I need them all to match in terms of units. This one is already in meters, so it's up to us to convert the others also into meters. So this is just gonna be unit, metric prefix conversions. So I'm gonna go from nanometers to meters. Nanometers goes on up at the bottom, meters goes on top. 1 nano is 10 to the negative 9. So this equals 5.95 times 10 to the negative 7 meters. For the next one, we're gonna go from centimeters to meters. So one centimeter is 10 to the negative 2 meters. Okay? So this is gonna come out to 3.03 times 10 to the negative 4 meters. Next, we can convert this into scientific notation so we can compare it better. This is 5.10 times 10 to the negative 4 meters. And then finally, this one is 291 micrometers. So remember, 1 micrometer is 10 to the negative 6 meters. So that's 2.91 times 10 to the negative 4 meters. We want the shortest or smallest wavelength, and that would be option a, light energy a, because it's 10 to the negative 7, whereas all the others are 10 to the negative 4. They are larger. So that one would be expected to have the shortest or smallest wavelength, which corresponds to the highest energy.
