Help A$AP please

A gamma ray might have a wavelength as long as an _____.

Select one:
a. atomic nucleus
b. apple core
c. atom
d. amoeba

Answer 1

The correct answer is
a. atomic nucleus

In fact, very high-energy gamma rays can have wavelengths as short as
`10^(-20) m`. For comparison, the size of the atomic nucleus is approximately
`10^(-15) m`, therefore we can say that gamma rays might even have wavelengths shorter than the size of an atomic nucleus.
