Which rays are not is the portion of \(e m\) waves?
1 \(X\)-rays
2 Microwaves
3 \(\alpha\)-rays

Which of the following rays are not electromagnetic waves?
1 \(\beta\)-rays
2 \(X\)-rays
3 \(\gamma\) - rays
4 Heat rays
Explanation:
\(\beta\)-rays are fast moving electrons. So, they are not electromagnetic waves. \(X\)-rays are electromagnetic waves having wavelengths from about \({10^{ - 8}}\;m\) to \({10^{ - 10}}\;m\) \(\gamma\) - rays are electromagnetic waves wavelength ranging from about \({10^{ - 10}}\;m\,{\rm{to}}\,{10^{ - 14}}\;m\) Heat rays can travel through vacuum by radiation process. They are electromagnetic waves.
