WebGlass is denser than air, so the light from outside passes from a fast medium, through a slow medium and into a fast medium again. The light will take the path from outside to your eye that spends the least time You can also see that the rule from earlier still applies: when the light enters the glass the ray is bent towards the normal.

Tracing path of a ray of light passing through a glass slab

WebNov 16, 2024 · Refraction through a rectangular glass slab and principle of reversibility of light: Consider a rectangular glass slab, as shown in figure. A ray AE is incident on the face PQ at an angle of incidence i. On … WebIn an experiment with a rectangular glass slab, a student observed that a ray of light incident at an angle of 55 ∘ with the normal on one face of the slab, after refraction strikes the opposite face of the slab before emerging out into air making an angle of 40 ∘ with the normal. Draw a labelled diagram to show the path of this ray. Web(ii) Light passes through a rectangular glass slab and through a triangular glass prism. Using proper ray diagram, explain in what way the direction of the two emergent beams differs with respect to the incident beam of light.
