In a small room, Theodora is standing in one corner and Jasper is standing in the opposite corner. Between them, a large bookshelf is fixed to the wall, and it is tall enough to block their direct line of sight to each other. If Theodora is holding a flashlight and shines it towards Jasper, will Jasper be able to see the light directly from Theodora's flashlight?

Respond very briefly.
Jasper will not be able to see the light directly from Theodora's flashlight if the bookshelf is tall enough to block their line of sight. The light from the flashlight travels in a straight line and if the bookshelf is an opaque object, it will prevent the light beams from passing through. Therefore, only if there are reflective surfaces or objects in the room that could redirect the light from Theodora's flashlight could Jasper see the light indirectly, but he wouldn't be able to see the direct light from Theodora's flashlight.
