Which of the following is visible to a person only because light from another source reflects off it?

- lightning
- flashlight
- cloud
- sun

    Three of those produce light. Which one does not?

  • Science -

    Sun produces light. So does flashlight and lightning.
    Rule out those, and you've got your answer!

    if you can take to away and you are left with lightning and flash light think about it think what one reflects off something

  • Science -

    It is cloud probably because the sun produces it's own light, the flashlight has batteries and produces light, and lightning is light! Because of the way the clouds fall on a certain day you may only see them at a certain time of day or when the light reflects off it from another light source. At first I thought it was flashlight because in the book it does not say if the flashlight is on or off and that could change the whole answer!

    Plasma is kinda like light
    Flashlights produce light
    Sun is obvious
    Clouds

    Clouds is the answer
    :D
