Question

In the light of Heisenberg uncertainty principle, which radiation photon can locate the position of electron in an atom most precisely?

• A. Microwave
• B. Visible light
• C. $X$-ray
• D. $\gamma$ -ray

Answer 1

The correct option is D $\gamma$ -ray

Heisenberg uncertainty principle,
$\Delta x\times \Delta P\ge h/4\pi$
so if we use lesser $\lambda$, we will get more precise position and electron will be obtained within atom.
