Hello! ^^
Welcome to Brainly! Blah-blah
We are so excited, to meet you!
Brainly, is a website for you for answering questions, asking for help! if you need too. Plus, if you answer questions with explanation, you can also become a moderator in here too! But, you are not allow to answer d.umb questions on brainly... Plus, please be careful cause now there is scammers, on brainly... and they may give you a virus... So if you see a question in that don't press that link, just report...
And I hope you, will enjoy in brainly!
Have a great day!

Answer:
The state of the person under the influence of alcohol
The place in which the memory was initially encoded for the retrieval of information.
Retrieval of information is generally better given similar rather than different contextual cues Motivational and emotional factors
These are also likely to affect recall and forgetting.
Explanation:
Explanation:
(a)
The photoelectric effect is the phenomenon in which the light of the particular frequency incidents on the material. Then the emission of the electrons from the surface of the material occurs.
This phenomenon could not be explained by Newtonian physics.
In Newtonian physics, the energy is not discrete. In quantum mechanics, the energy is discrete. This is the main why the photoelectric effect could not be explained by Newtonian physics.
(b)
Light consists of photons. The photon is a packet of energy. It is also called quanta. The energies of the photons are quantized.
When a photon strikes on the surface of metal then the energy of photon is absorbed by an electron in the metal so that it may eject from the surface. This phenomenon is called the photoelectric effect.
(c)
In quantum mechanics, wave-particle duality concept is used to explain the wave-particle nature of the light. Light behaves as particle as well as wave. It shows both nature. The photoelectric phenomenon shows the particle nature of the light. It acts as a particle when it hits the surface of the metal.
In line spectra, the electron is excited to an energy level. In this case energy is transferred from photon to electron. There is a collision between photon and electron. The change in momentum will occur. It shows the particle nature of the light.
