Hello, regarding the photoelectric effect I had a couple questions:
Red light is shining on a simple photoelectric cell producing electric current at some voltage. Suppose we increase the intensity of the (red) light.
a. Will the current increase, decrease, or remain the same? Explain.
b. Will the voltage increase, decrease, or remain the same? Explain.
Suppose again that we start with red light shining on a simple photoelectric cell producing electric current at some voltage. Now we change from red light to blue light (without changing the intensity of the light).
a. Will the current increase, decrease, or remain the same? Explain.
b. Will the voltage increase, decrease, or remain the same? Explain.

The photoelectric effect is observed by shining blue monochromatic light having wavelength 450 nm onto a sample of caesium. The collector electrode is biased to a voltage V relative to the caesium potential (a) Use the Internet to look up the workfunction of caesium (b) Find the most negative value of V, the retarding potential, at which a photocurrent may be observed (c) What is the longest wavelength of radiation that would allow photocurrent from the caesium to be observed...

PHOTOELECTRIC EFFECT LAB Enter your answers to Canvas. Objectives: The main objective of this lab is to observe the photoelectric effect experiment qualitatively. From the observations, you will summarize the important relationship between the properties of the photoelectrons (average speed, kinetic energy) to the properties of the incident light (wavelength, frequency).

Hello guys,
Here are a couple of questions from my Chemistry text book, that
I would like to learn how to figure out, some of them already have
answers, but I don't get how the answers were found, some of them
have some algebra attached and I am bad with algebra so I want to
learn how the steps were done, and some of them are ones that I
have done a little of but I am stuck in.

dielectric spectroscopy glucose reading (DSGR) is
a noninvasive diagnostic technique that uses the electric
capacitance of blood to estimate blood glucose levels.
A DSGR device records the electric current that results from
applying a voltage source to the skin and underlying blood vessels.
DSGR can be modeled by the circuit shown in Figure 1, in which V
represents the applied potential, CB represents the...
