can microwave be used in the experiment on photoelectric effect
Answers
Answer:
The results shown that Microwave “photoelectric effect” makes water adsorbing on the surface of Microwave catalyst to transform into ∙OH. ... Generally photons of MW electromagnetic wave could not directly excite catalyst to produce electron-hole pairs (e−cb-h+vb) because of the lower energy of photons.
Answer:
Explanation:
No.
The photoelectric effect is totally a Quantum Physics phenomenon. A single photon of light delivers it’s tiny bundle of energy to the metal and ejects a single electron with a very precise energy balance.
Electric sparks emitted from metal points/edges in a microwave oven are a macroscopic phenomenon that has no need for a quantum explanation. The microwave generator pumps hundreds of watts of electromagnetic energy into the oven cavity. The microwaves have a frequency of 2.4 gigahertz which gives them a wavelength of about 12 cm. (About 4 3/4 inches for those in the US)
These intense electric fields induce currents to flow in the metal. Sharp points/edges concentrate the buildup of the electrons which can locally increase the voltage enough to cause the arcing.
