CAN YOU PLEASE HELP?! how light interacts with matter?

listed are various physical situations that describe how light interacts with matter. match these to the appropriate category.

transmission absorption reflection or scattering emission

1) white light hits a white piece of paper

2) visible light does not pass through a black wall

3) visible light meets clear glass

4) light comes from a light bulb

5) blue light hits a red sweatshirt

6) cell phone signals pass through walls

7) light comes from your computer screen

8) red light hits a red sweatshirt

THANKS SO MUCH! I AM STUCK AS CAN BE!

  • 1) white light hits a white piece of paper

    8) red light hits a red sweatshirt

    Scattering (random) or Reflecting (in organized direction) = when the light is bounced back

    2) visible light does not pass through a black wall

    5) blue light hits a red sweatshirt

    Absorption = when light is absorbed and not bounced back

    3) visible light meets clear glass

    6) cell phone signals pass through walls

    Transmission = whenever light goes through something

    4) light comes from a light bulb

    7) light comes from your computer screen

    I don’t know what to do with these from your list — these are in fact emitting light; they cerrtainly aren’t absorbing, but if they mean that the light goes through the glass of the light bulb or the pane of the screen, that could be transmission; or it could be scattering.

  • Don’t take my answers as gospel.

    1. Scattering

    2. Absorption

    3. Transmission

    4. Emission

    5. Absorption

    6. Transmission

    7. Emission

    8. Scattering

  • Air is not as dense as a table or a phone. Particles of the air are far apart from each other than the particles of a table or a phone. Particles of air are very very small so the reflection is not perceivable. If air contains bigger particles say dust particles these are big enough to reflect light that can be seen by our eyes. I don’t think electromagnetism has anything to do with the phenomenon.

  • I think Kurt’s got it.

    4 and 7 are scattering emission.

  • Doesn’t anyone do their own homework anymore???
