I think that you didn't copy the answers correctly, because 1 and 2 are the same, and 3 and 4 are also the same here.
Anyways, the answer which is correct is that an electron has a charge of -1, and a proton has a charge of +1.
Electrons are negatively charged, whereas protons are positively charged. Neutrons are neutral.
Each type of electromagnetic radiation and placed in order of increasing photon energy and increasing frequency
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays
This is further explained below.
<h3>What is
electromagnetic radiation?</h3>
Parameters
Frequency =107 100 000 hertz
Wavelength, λ = c / ν => 2.8 m => 2.12 * 10-10 m
Energy = 3.97 * 10 -19 J/ photon.
Generally, the equation for Wavelength is mathematically given as
λ = h c / E
Therefore
λ =6.626 * 10-34 * 3 * 108 / (3.97* 10 -19 J)
λ =5 * 10-7 m
In conclusion, This is considered to be part of the viewable area (green Increasing photon energy from lowest to highest.
- FM Radio waves < Visible light < X - rays
- Order of increasing frequency.
- FM Radio waves < Visible light < X - rays
