Answer:
X ray
Explanation:
To see an object the light used must have the same or smaller wavelength than the object. The size of an atom is about m, smaller than the wavelength, therefore we'll need radiation with a shorter wavelength <em>since X-ray wavelengths are about the same size as atoms this characteristic makes it ideal to use.</em>

The correct answer is <span>nebula forms → nebula collapses → protostar forms → fusion begins</span>
<span>The mass of an electron is not significant to the overall mass of the atom. (B)
It takes roughly 1,850 electrons to equal the mass of ONE proton or neutron,
but the most complex atom has only around 100 of them.</span>
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
