The energy per mole of photons for the laser used in Blu-ray players is to be calculated. Concept introduction: Planck’s equation, E = hν where, E = energy h = Planck's constant ν = frequency The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases. The frequency of the light is inversely proportional to its wavelength. ν = c λ where, c = speed of light ν = frequency λ = wavelength

Chapter 6.2, Problem 1CYU
Interpretation Introduction

Interpretation: The energy per mole of photons for the laser used in Blu-ray players is to be calculated.

Concept introduction:

  • Planck’s equation,

    E=where, E=energyh=Planck'sconstantν=frequency

The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases.

  • The frequency of the light is inversely proportional to its wavelength.

  ν=cλwhere, c=speedoflightν=frequencyλ=wavelength
