What happens to a light wave that travels through glass and strikes a boundary with water at a 45° angle?
A. It reflects back into the glass with a 45° angle of reflection.
B. It reflects back into the glass in the direction it was traveling from.
C. It refracts in the water, toward the boundary.
D. It refracts in the water, away from the boundary.

D

it reflects back into the air moving the opsite direction.

i hope this helps :)

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
