Answer:
Explanation:
The refractive index of liquid with respect to glass = sin of Angle of incidence in glass / (sin of angle of refraction in liquid )
The refractive index of liquid with respect to glass = sin 40 / sin 55
refractive index of liquid / refractive index of glass = sin 40 / sin 55
refractive index of liquid / 1.60 = sin 40 / sin 55
refractive index of liquid = 1.6 x sin40 / sin 55
= 1.6 x .642 / .819
= 1.254 .
