Which of the following statements apply to the photoelectric effect? 1) wave theory accurately describes the photoelectric effect. 2) quantum theory accurately describes the photoelectric effect. 3) the photoelectric effects can be explained in the same way that diffraction and interference are explained. 4) the photoelectric effect offers evidence of the wave nature of light. 5) the photoelectric effect demonstrates that photons are small enough to interact with individual electrons.

correct ans is (2)

The classical model of light depicts diffraction and interference. Quantum theory precisely depicts the photoelectric impact since when Einstein initially proposed the utilization of light quanta to clarify the photoelectric impact. This idea is formalized in the quantum theory of radiation. The photoelectric effect explain, If you  light of sufficiently high energy on to a metal, electrons will be emitted from the metal. Light beneath a specific threshold frequency, regardless of how extreme, won't make any electrons be radiated. Light over the threshold frequency, regardless of whether it's not extremely intense, will dependably motivation electrons to be transmitted.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
