When using a Photocell, what responses are expected with a change in light?
Homework Answers
Photocells are resistors that change their resistance value depending upon the light falling on it.
For the photoelectric effect to take place, the frequency of the incident light should be more than the threshold frequency.
If the intesity of the incident radiation is increased then the current increases. Intensity is basically the number of photons falling on the photocell. More the number of photons more is the electrons generated and hence more is the current.

When light hits a surface of a vacuum photocell with light of wavelength 555 nm electrons are barely ejected from the surface. You change the excitation wavelength to 401 nm. Calculate the ejected electrons kinetic energy and velocity. I would need the complete solution to understand the answer. Many thanks

A device called a photocell detects light by letting it fall onto a metal and then measuring the current from the ejected electrons. You are designing a photocell to work with visible light and are considering the use of either molybdenum (work function = 4.2 eV) or sodium(work function = 2.4 eV). What is the lowest photon frequency that can be detected with your photocell?

The maximum wavelength of light a certain silicon photocell can detect is 1.07 μm. What is the bandgap, in eV, of the semiconductor material? (answer to 2d.p.)
A "pulse oximeter operates by using light and a photocell to measure oxygen saturation in arterial blood
A "pulse oximeter operates by using light and a photocell to measure oxygen saturation in arterial blood. The transmission of light energy as it passes through a solution of light-absorbing molecules is described by the Beer-Lambert law which gives the decrease in intensity I in terms of the distance L the light has traveled through a fluid with a concentration C of the light-absorbing molecule. The quantity ε is called the extinction coefficient, and its value depends on the frequency of...

In a physics lab, light with a wavelength of 560 nm travels in air from a laser to a photocell in a time of 17.2 ns . When a slab of glass with a thickness of 0.880 m is placed in the light beam, with the beam incident along the normal to the parallel faces of the slab, it takes the light a time of 21.0 ns to travel from the laser to the photocell. What is the wavelength of...

A phototube in a photoelectric device has a photosensitive element. When light of wavelength 389.2 nm is shone on this surface, electron are emitted with a maximum kinetic energy of 1.589 x 10^-19 J/electron. What is the wavelength of a laser which will turn the photocell on and cause electrons to be ejected which have no excess energy?
