Answer 1

Answer #1

Givein in the question,

Frequency of the photon, n = 4 × 10¹⁶ Hz

Now, energy of a photon havin frequency n Hz is,

E = h × n

Hare, h= planck's constant

= 6.626 × 10^-34 J.s

Thus energy in electron volt,

E = (h×n)/e = ( 6.626 × 10^-34 × 4 × 10¹⁶)/ (1.6 × 10^-19 ) = 165.65 electronvolt.

Answer, E = 165.65 eV.

PLEASE HELP WITH THESE THREE QUESTIONS What is the orbital frequency (in Hz) of the electron as it orbits about the nucleus in the n = 100006 state of the Hydrogen atom? You can obtain this from the Bohr Model of the Atom by using the equations for the radius of the orbit and the speed of the electron. Since the orbital frequency is the number of revolutions per second that the electron undergoes as it orbits, you can determine...
