A student while doing the experiment on tracing the path of a ray of light passing through a rectangular glass slab measured the three angles marked as θ1, θ2 and θ3 in the figure.His measurements could be correct if he were to find:(1) θ1 < θ2 < θ3 (2) θ1 < θ2 but θ1 = θ3 (3) θ1 > θ2 > θ3 (4) θ1 > θ2 but θ2 = θ3 |
