Physics - Photoelectric effect Exam with Questions and Answers How does a X-ray machine work? ANSWER Hits target with electrons and electromagnetic radiation flies out How does electromagnetism relate to the photoelectric effect? ANSWER You hit the target with electromagnet radiation and electrons fly out - these are known as photoelectrons Cutoff wavelength ANSWER No photoelectrons get ejected no matter how great the intensity of the incident - meaning you can't see the light anymor...

Photoelectric effect correct answers -When light of a sufficiently high frequency (typically blue to ultraviolet light) is incident on a metal in a vacuum, the metal atoms emit electrons. -albert einsteins 1905 explanation of the photoelectric effect won him the nobel prize. -Electrons liberated from the metal produce a current. -light beams of greater intensity produce larger current in this way. -higher the intensity of the light beam, the greater the number of photons per unit t...

The principal late effects of ionizing radiation on humans include tissue damage ic effects nant disease - ANS ic effects nant disease Late or long-term effects of radiation can occur in tissues as a result of chronic exposure or tissues that have survived a previous irradiation months or years earlier. These late effects, such as carcinogenesis and genetic effects, are "all-or-nothing" effects—either the organism develops cancer or it does not. Examples of late effects of ...
