(Colloids can be distinguished from solutions using the Tyndall effect.) Light passing through a colloidal dispersion, such as smoky or foggy air, will be reflected by the larger particles and the light beam will be visible. So, if your room is quite dusty.. or there are dust particles in your room, light would be reflected. We discussed this in class.

Answer 2

it all depends on wot the conditions r out side tho? coz u could get reflectoins from car lights & so on. if sealed room for instance them maybe mind playing tricks or who knows even another dimention crossing over into ours brefly?

Answer 3

Dust, smoke, mist, other particles in the air that reflect some of the light.

Answer 4

Richie P is a strange, strange person.  It is definitely NOT another dimension intersecting our own.

The reason is that light bounces off particles of dust or other matter in the air, creating the appearance of a "shaft" of light stretching across the room.
