Question∵
Compared to visible light, an electromagnetic wave that has a longer wavelength will also have?
Answer:
Hi, There! -Randp12- My Name Is jay I'm here to help! :)
<u><em>The correct answer is lower frequency.</em></u>
Explanation:
Information to Support My Answer :D
it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.
Therefore for higher wavelength, the electromagnetic wave will also have lower frequency.
Hope this helps!

Answer:
That the isotope H-1 is the most abundant in nature.
Explanation:
Hello!
In this case, since the average atomic mass of an element is computed considering the mass of each isotope and the percent abundance each, for hydrogen we would set up something like this:
Moreover, since the isotope notation H-1 and H-2 means that the atomic mass of H-1 is 1 amu, that of H-2 is 2 amu and the average one is 1.0079 amu, we can infer that the most of the hydrogen in nature is H-1 as the most of it composes the average hydrogen atom.
Best regards!
