Activity 1
We observed that when light ray travels from air to the plastic rectangular block, the refracted ray moves towards the normal.
When the light ray travels from plastic to air, the refracted ray moves away from the normal.
It is observed that when the angle of incidence is 0 , there is no refraction.
Activity 2
The angle is 45 degrees when there is no longer any refraction.
What about your observations as you increase the angle of incidence from 10 degrees to 40 degrees?
ReplyDeleteWhat did you observe about the refracted ray and angle of refraction?
What did you observe about the reflected ray?
