Refraction - Elijah and Kieren

Activity 1
We observed that when light ray travels from air to the plastic rectangular block, it bends towards the normal.
When the light ray travels from plastic it bends away the normal.

It is observed that when the angle of incidence is 0 there is no refraction.
Activity 2

Angle of incidence 30 degrees.
Angle of incidence 50 degrees.
There is an angle when there is no longer any refraction. The angle is 45° .
Angle of incidence 90 degrees.

  1. Good. However, you can give more details for Activity 2 in your description on difference as the the angle of incidence increases.
