Question:

The energy of gamma $(?)$ ray photon is $E_?$ and that of an X-ray photon is $E_x$. If the visible light photon has an energy of $E_v$ , then we can say that

Updated On: Apr 19, 2024
  • $E_x > E_? > E_v$
  • $E_? > E_v > E_x$
  • $E_? > E_x > E_v$
  • $E_x > E_v > E_?$

The Correct Option is C

Solution and Explanation

$E_{\gamma} \geq 100 keV$ $ E_{X} =100\, eV$ to $100 \,keV $ $ E_{v} =2.48\, eV $ So, we can say that $E_{\gamma}>E_{X}>E_{v}$

Nuclei

In the year 1911, Rutherford discovered the atomic nucleus along with his associates. It is already known that every atom is manufactured of positive charge and mass in the form of a nucleus that is concentrated at the center of the atom. More than 99.9% of the mass of an atom is located in the nucleus. Additionally, the size of the atom is of the order of 10-10 m and that of the nucleus is of the order of 10-15 m.
