Question

Which of these does not result directly in reflection?

shining light from a spacecraft into space

shining light on the surface of a deep lake

light from a submerged light source aimed upward at the water surface

light incident on a sheet of paper

Answer 1

stuck between A and C

Answer 2

why do you say A?

Answer 3

you have correctly narrowed the choices down to two possible answers (A+C). I'll try to help you narrow it down to the right one.

In order for light to reflect, it must bounce off a surface/object. Between A & C, try to consider which of these situations is more likely to result in light bouncing off a surface.

Answer 4

I think it would be C, to be more likely to result in light bouncing off a surface. So that would then make the answer B ? right ?

Answer 5

hm? Nah, it wouldn't be B (if you shine light on water, it'll bounce off the water)

like I said in the previous post, you correctly narrowed it down to A and C, and now that you've eliminated C, A is the solution c:

light could *theoretically* reflect off something in space, but it's much less likely/would take a lot longer than reflecting off a lake

Answer 6

ohhh okay , yes this makes sense! Thank you for explaining that
