Tina's science teacher shines a laser onto a screen. It is brighter than the white light from the laboratory lights. Use your ideas about frequency to explain the difference between laser light and white light.
Answer (2)
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.
Laser light is different from white light in that it consists of a single wavelength and has coherent properties, while white light is made up of many wavelengths. This monochromatic characteristic of laser light results in a more focused and brighter appearance compared to the diffuse nature of white light. The energy of laser photons is also higher due to their higher frequencies compared to the mixed wavelengths of white light.
