Give the relation of energy (E) and frequency (v) as given by Planck. Calculate the frequency and energy of a photon of radiatio
andrew-mc [135]

<u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u><u>1</u>

\\ \sf\longmapsto E=hv

  • E denotes to Energy
  • h denotes to planks constant
  • v denotes to frequency.

<u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u><u>2</u>

  • Wavelength=3000Å

\boxed{\sf \lambda=\dfrac{c}{v}}

\\ \sf\longmapsto v=\dfrac{c}{\lambda}

\\ \sf\longmapsto v=\dfrac{3\times 10^8m/s}{3000\times 10^{-10}m}

\\ \sf\longmapsto v=0.001\times 10^{18}s^{-1}

\\ \sf\longmapsto v=1.0\times 10^{15}s^{-1}

Now

\\ \sf\longmapsto E=hv

\\ \sf\longmapsto E=6.626\times 10^{-34}Js\times 1.0\times 10^{15}s^{-1}

\\ \sf\longmapsto E=6.6\times 10^{-19}J
