The width of a plane incident wavefront is found to be doubled in a denser medium. If it makes an angle of 70° with surface, calculate the refractive index for the denser medium.
Given: i = 70°, CD = 2AB
To find: Refractive index (μ)
(\therefore) μ = 1.288
The refractive index for the denser medium is 1.288.
