As a verb, to do; to produce; to make; to bring to pass; to execute; enforce; accomplish. As a noun, that which is produced by an agent or cause; result; outcome; consequence. The result that an instrument between parties will produce in their relative rights, or which a statute will produce upon the existing law, as discovered from the language used, the forms employed, or other materials for construing it. The operation of a law, of an agreement, or an act. The phrases take effect, be in force, and go into operation, are used interchangeably.

In the plural, a person's effects are the real and Personal Property of someone who has died or who makes a will.

"Photoelectric effect shows that colours have different energies and the dancers are in white to start with and by the end they are in crazy rainbow colours.
Ironically, the Nobel Prize for physics was awarded to Einstein in 1921, not for his relativity theory but for his work on the photoelectric effect. Today, physicists regard Einstein's relativity theory as one of the most comprehensive pictures of the universe.
* Albert Einstein's explanation of the photoelectric effect won him the Nobel Prize for physics in 1921.
One of the 1905 papers gave a radical explanation of the photoelectric effect. Max Planck, in his explanation of blackbody radiation five years earlier, had with considerable reluctance used a formula suggesting that material substances can interact with radiation only by transfer of energy in finite amounts, not continuously.
This photoelectric effect turned out to be extremely important.
The Nobel Prize in Physics was awarded to Robert Andrews Millikan of the California Institute of Technology for his "work on the elementary electric charge and on the photoelectric effect" while professor of physics at the University of Chicago from 1906 and 1916.
In 1921 he was awarded the Nobel Prize in Physics for his studies in the motion of the atom, the photoelectric effect, gravitation - and - inertia, and the space - time continuum, the inter - relatedness of which he demonstrated in The Meaning of Relativity (1921).
He developed the theory of general relativity and advanced the law of photoelectric effect. His work earned him a Nobel Prize in 1921, and in 1999, the Time magazine named him "Person of the Century."
The six other pieces in that puzzle, including Dirac's 1930 theory on the annihilation of electrons and positrons and Einstein's 1905 theory on the photoelectric effect, are all associated with Nobel Prize-winning research (see image).
Photovoltaic, a device that converts light into electric current using the photoelectric effect or we can say that it converts incident light of sun into electricity.
Namely, X-ray photons with energies of 90 and 140 keV lead to atom ionization by photoelectric effect, and also this process is more dominant for lower photon energies (in our case this was for energies of 90 keV).
