Observation of refraction of light for project
Answers
Answer:
when the light reflection of the light rays fall on the project.
Answer:
When light from an object (like a pin) passes through an optically denser medium (like glass), it appears to be behind its original position.
On the other hand, if light passing from a denser to rarer medium (for eg. from glass to air), the object of which the light appears to be ahead of its actual position.
Explanation: In the first case, when the light enters the glass medium, it bends towards the normal at the point of incidence of the plane, thus when the virtual rays are produced backwards, the object appears to be behind its actual position.
In the second case, when the light rays travel from glass to air, the rays bend away from the normal at the point of incidence at the plane, and the virtual rays produced backward meet the normal at the point of incidence ahead of its real position, thus appearing to be ahead of its actual position.
