Answer 1

Answer:

1.An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface.

2.pupil become large in dim light, so that more and more light can enter in eyes. pupil become smaller in bright light, to reduce the amount of light enter in eyes. Pupil becomes larger in dim light, so that more and more light can enter in the eyes.
