In an experiment searching for the photoelectric effect, an incident beam of green light produced no ejected electrons from a metal. In order to eject electrons, the experimenter should? A. increase the brightness of the light. B. try blue light. C. try yellow light. D. give up on that particular metal. E. decrease the brightness of the light.
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...
Problem (8 points) For the Photoelectric Effect experiment shown, when ultraviolet light with a wavelength of 240 nm shines on a particular metal plate, electrons are emitted from plate 1, crossing the gap to plate 2 and causing a current to flow through the wire connecting the two plates. The battery voltage is gradually increased until the current in the ammeter drops to zero, at which point the battery voltage is 1.40 V plate 2 AV incident ◇e electrons Tammeter...
Please show all work and answer all parts. Thank you!
1. In the photoelectric effect, incident blue light on a metal Incoming blue light (abeled the "emitter") causes cellector plate mitter plate electrons to be emitted from the surface. All such emitted electrons have the same speed. The electrons go zooming off to the collector plate (another metal plate, see figure at right). The collector and emitter can be held at a fixed potential difference by a Let's assume the...
In an experiment to test the photoelectric effect, Divya shines a 450 nm blue laser at a sodium target. This produces a current I in a circuit she is using to detect the electrons emitted. Which of the following changes in her experimental setup would double the current in the circuit to 2I ? (The work function of sodium is approximately 2.36 eV.) Double the intensity of the 450 nm blue laser. Replace the laser with a 900 nm infrared...

Quantized and total photon energy The particle characteristics of electromagnetic radiation are responsible for the quantized behavior of light energy. This behavior explains the results of varying the intensity and wavelength for an observed photoelectric effect, which describes the emission of electrons when light shines on a metal surface. If light only exhibited a purely wavelike behavior, then either increasing the intensity or decreasing the wavelength would both increase the rate at which electron are emitted. However, monochromatic light of...
