- Fresh out of university you've been hired to do some photoelectron spectroscopy. You have a lamp that outputs an unknown wavelength of light. When the light is incident on a metal with a work function of 6.31 eV, you observe a stopping voltage equal to 4.21 V. What is the wavelength of the light? (unit in nm).arrow_forwardWhen we illuminate lead with ultraviolet light with a wavelength of 250 nm, suppose we find the maximum potential difference developed between the plates in the experimental setup shown in the figure to be 0.82 volts. From these data and the accepted value of hc, find the potential difference between the plates if the wavelength is 215 nm. Also find W for lead.arrow_forwardThe work function of cesium is 1.6 x 10-19 J. Calculate the maximum speed of the electrons emitted when yellow light is used (λ = 0.589 μm), in meters per second.

- The de Broglie wavelength of an electron has to do with spatial resolution of an electron microscope, which is often expressed in the unit of length Å (Angstrom). The 1 V potential difference causes an electron to gain kinetic energy EK of 1 electron Volt (eV). In the SI units, kinetic energy in eV must be converted to Joules. The conversion factor is 1 eV = 1.6 x 10-19 Joule. And, the formula for the wavelength is: λ = h / p = h / √(2 m EK) where m is electron mass. Calculate the de Broglie wavelength of an electron (in Å) when the electron is accelerated from rest through a potential difference of: a) 1 kV = 1,000 V (a low resolution setting of microscope), b) 10 kV = 10,000 V (intermediate resolution). c) 100 kV = 100,000 V (high resolution),arrow_forwardModel the tungsten filament of a lightbulb as a black body at temperature 2 900 K.
