Solutions

Chapter 6, Problem 64GQ
Interpretation Introduction

Interpretation: The number of photons with λ=12cm has 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

  • The specific heat capacity can be calculated as,

  Q=mCpΔTwhere,Q=specificheatcapacitym=massCp=specificheatΔT=changeintemperature
