I already answered this question here: https://brainly.com/question/3641300, but I will answer it again for you.
At angle B, the light is refracted as it enters the glass. As it exits the glass and re-enters the air at angle C, it is refracted at a different angle in the opposite direction from B.
At angle B, the light is refracted as it enters the glass. As it exits the glass and re-enters the air at angle C, it is refracted at a different angle in the opposite direction from B.
Answer:
The refraction is the property when the light strike a plane and that light passes through the plane.
So, we can clearly see from the picture shown that the refraction line is the point at B and C
The angle made from normal line is the angle of refraction.
And the line that strikes the plane and comes back is reflection.
