Question

2. (a) If refractive indices of kerosene oil, turpentine oil
and water are 1.44, 1.47 and 1.33 respectively. In which of
them, speed of light will be maximum and why?
in numerical​

Answer 1

Refractive index of water (1.33) < Refractive index of kerosene (1.44) < Refractive index of turpentine (1.47). Hence, Speed of light in water (fastest) > Speed of light in kerosene > Speed of light in turpentine (slowest).
