The question is : Tina's science teacher shines a Lazer onto a screen .it is brighter than the white Light from the laboratory lights. Use your ideas about frequency to explain the difference between Lazer light and white light?

Answer :

MODERATOR: Bogus & misleading question. If frequency were relevant, it would say something about the color of the "Lazer". And "white light" doesn't have a frequency ... it has all of them. Next, you can compare the energy of one photon of each, but not of a beam of each. If a classroom laser is brighter than the lights in the room, then it is definitely hazardous. Finally, almost all small laser pointers are red ... LESS energy per photon than any other visible light in the room.
