Two of the types of ultraviolet light, uva and uvb, are both components of sunlight. their wavelengths range from 320 to 400 nm for uva and from 290 to 320 nm for uvb. compare the energy of microwaves, uva, and uvb. rank from greatest to least energy per photon. to rank items as equivalent, overlap them.

uvb > uva > microwaves

Explanation:

The energy of an electromagnetic wave is

Where

h is the Planck's constant

c is the speed of light and

is the frequency

So we can understand that the energy is inversely proportional to the wavelength

The wavelengths are

1.microwaves - 1 mm - 1m

2.uva - 320 - 400 nm

3.uvb - 290 - 320 nm

So with the smallest wavelength the uvb has the greatest energy

and the microwave has least amount of energy with the largest wavelength range

so the answer is uvb > uva > microwaves

unable to answer the rest since your question is incomplete

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
