Problem

Light travels from water (

n=1.33

) into an unknown transparent medium. The refracted ray bends away from the normal. Which of the following conclusions about the refractive index

\mu

of the unknown medium is correct? (a)

\mu = 1.33

(b)

\mu \approx 1.53

(c)

\mu < 1.33

(d)

\mu

depends only on wavelength, not on direction of bending
