Sep 9, 2022 · Since they are small enough to be considered quantum particles, photons can exist as waves, with a wavelength (λ) corresponding to the distance between each repeating point in the wave. Frequency (f) is a measure of how ‘frequently’ a wave appears within a period of time.

When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength (or equivalently, above a threshold frequency), the incident radiation is absorbed and the exposed surface emits electrons. This phenomenon is known as the photoelectric effect.
Explain the relationship between the energy of a photon in joules or electron volts and its wavelength or frequency. Calculate the number of photons per second emitted by a monochromatic source of specific wavelength and power.
Oct 19, 2017 · The photon model equation relates the frequency and energy of a photon together by a constant of proportionality, where #E\proptof=>E=hf#, where: #E# is the energy of the photon (#J#) #f# is the frequency of the photon (#s^(-1)#) #h# is Plank's constant (#~~6.63*10^(-34)Js#)
Explain the relationship between the energy of a photon in joules or electron volts and its wavelength or frequency. Calculate the number of photons per second emitted by a monochromatic source of specific wavelength and power.
Use Equation \(\ref{6.2.1}\) and the relationship between wavelength and frequency to calculate the energy in joules. Solution: The energy of a single photon is given by \[E = h\nu = \dfrac{hc}{λ}.\]
