What is the energy ( in eV) of a photon of walelength `12400A`?

Text Solution

AI Generated Solution

To find the energy of a photon with a wavelength of \( 12400 \) Å (angstroms), we can use the formula for the energy of a photon: \[ E = \frac{hc}{\lambda} \] Where: - \( E \) is the energy of the photon, ...

Photoelectrons are emitted when 400 nm radiation is incident on a surface of work - function 1.9 eV. These photoelectrons pass through a region containing a-particles. A maximum energy electron combines with an a -particle to from a He^+ ion, emitting a single photon in this process. He^+ ions thus formed are in their fourth excited state. Find the energies in eV of the photons lying in the 2 to 4 eV range, that are likely to be emitted during and after the combination. [Take, h = 4.14xx10^(-15) eV -s]
