Why photoelectric measurement are so sensitive to the nature of photoelectric surface?
Photoelectric measurements are sensitive to the nature of the photoelectric surface because the surface properties, like work function and reflectivity, directly affect the efficiency of electron emission when photons are absorbed. The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.
What effects did scientists originally think that the intensity of light shining on a photosensitive surface would have on electrons ejected from that surface?
Scientists originally thought that the intensity of light would affect the number of electrons ejected, but not their energy. They believed that increasing the intensity would only result in more electrons being emitted from the surface, without impacting their kinetic energy.
How does the intensity of light affect the electrons emitted from a metal?
Increasing the intensity of light results in more photons hitting the metal surface, which can increase the number of electrons emitted through the photoelectric effect. This can lead to a higher current of ejected electrons being generated.
Which particles affect the charge of an atom or ion?
The particles that affect the charge of an atom or ion are electrons and protons. Electrons have a negative charge and protons have a positive charge. The number of electrons and protons in an atom or ion determines its overall charge.
How do different metals affect emission of electrons?
Different metals have different work functions, which determine the amount of energy required to remove an electron from the surface of the metal. Metals with lower work functions typically exhibit higher electron emission because it requires less energy to release an electron. Additionally, the surface properties of the metal can affect electron emission, such as roughness or cleanliness, which can impact the efficiency of the emission process.

What affect might be caused by electrons being loosely bound to atoms in a material?
1. Chemical bonding 2. Photo electric emission 3. Electric current flow 4. Radiation emission
Why photoelectric measurement are so sensitive to the nature of photoelectric surface?

The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.
What factors affect Emission spectra?
i.)work function of the substance should be low ii.)melting point of the substance

What do atoms do when electrons move energy levels?
Atoms don't do anything. If the electrons go to a higher energy state, they use energy. If they fall back to a lower state, they release energy. This shouldn't affect the entire atom, just the electrons.
How does a mitochondrions structure affect its function?
Abnormal death of the cells due to dysfunction of mitochondria can affect its function.
How does the intensity of light affect the electrons emitted from a metal?
Increasing the intensity of light results in more photons hitting the metal surface, which can increase the number of electrons emitted through the photoelectric effect. This can lead to a higher current of ejected electrons being generated.
How does the structure affect its function?
The mitochondrial structure affects its function because in its inner membrane, the cristae (folds) allow for more surface area which increases the amount of ATP that can be produced by the mitochondria.
