Vedclass · Answer

(B) When light travels from a medium of higher optical density to a medium of lower optical density,it bends away from the normal.Here,the refractive index of turpentine $(n_t \approx 1.47)$ is greater than the refractive index of water $(n_w \approx 1.33)$.Since light is moving from turpentine to water,it is moving from a denser medium to a rarer medium.Therefore,the refracted ray must bend away from the normal at the interface.Looking at the provided figure,ray $2$ shows the path bending away from the normal when entering the water from the turpentine layer.Thus,the correct path is represented by ray $2$.

The optical density of turpentine is higher than that of water,while its mass density is lower. The figure shows a layer of turpentine floating over water in a container. For which of the four rays incident on the turpentine as shown in the figure,is the path correct?
