The photoelectric effect experiment demonstrated that electrons are emitted from a material when it is exposed to light of a certain frequency, regardless of the light's intensity. This discovery contributed to the development of quantum theory and helped support the idea that light behaves as both a wave and a particle.

Who discovered the cathode ray experiment?
The cathode ray experiment was discovered by British physicist J.J. Thomson in 1897. Through this experiment, he was able to demonstrate the existence of negatively charged particles (electrons) and their properties.
What is millicon's oil drop experiment?
The Millikan oil drop experiment was conducted by Robert Millikan in 1909 to measure the elementary electric charge (the charge of a single electron). In the experiment, tiny oil droplets were suspended in a chamber between two charged plates. By carefully controlling the electric field, Millikan was able to measure the charge on each droplet and determine the charge of a single electron. This experiment provided important evidence for the quantization of electric charge and contributed to the development of modern atomic theory.
Which experiment Faraday did about clue of electron?
Faraday's experiment with electrolysis provided clues about the existence of electrons. He observed that when an electric current passed through an electrolyte solution, elements were deposited at the electrodes in specific ratios, indicating the presence of fundamental particles carrying electric charge.
What is a semiconductor device that produce electric current through the photo-voltaic is an?
A semiconductor device that produces electric current through the photo-voltaic effect is a solar cell. When sunlight shines on the cell, it creates an electric current by releasing electrons from the material. This electric current can then be harnessed for various applications, such as generating electricity for homes or powering electronic devices.
What did Oersted conclude from his experiment?
Oersted concluded from his experiment that an electric current produces a magnetic field. This discovery established the relationship between electricity and magnetism, leading to the development of electromagnetism theory.
What is the method used to demonstrate an experiment or imitate a phenomenon?
method used to demonstrate an experiment or to imitate a phenomenon
What is photo electric?
when photons got enough energy and getting out from that meterial electric current produced from that movement called photo electric.
Who invented the electric power station?
Thomas Edison invented the first electric power plant.
Are alkali metals suitable for photo electric emission?
yes alkali metals are suitable for photo electric emission
When scientists do repeated tests to discover or demonstrate something they conducting an?
experiment
Are all metals useful for photo electric effect?
The photoelectric effect can be demonstrated using any metal. But for some ofthem, you might have to come up with a source of inconveniently-high-energyE&M radiation in order to demonstrate it.
What does the visual cliff experiment demonstrate?
Eleanor J. Gibson and R.D. Walk, psychologists at Cornell University created the visual cliff apparatus. The experiment was meant to investigate and demonstrate depth perception in human and animal species.
What are some examples of an experiment?
Experiment can be scientific or psychological. They can use samples and observations to gain insight or mix chemicals together to demonstrate reactions.
Proofs of the particle nature of light?
Albert Einstein's Photo-electric effect is one of the proof of the particle nature of light. The experiment on the wave particle duality is another proof pf the particle nature of light.
Is the noun experiment an abstract or concrete noun?
The noun experiment is an abstract noun, a word for a process used to demonstrate, discover, or test a hypothesis; a word for a concept.
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
Who discovered the cathode ray experiment?
The cathode ray experiment was discovered by British physicist J.J. Thomson in 1897. Through this experiment, he was able to demonstrate the existence of negatively charged particles (electrons) and their properties.
