Answer:
a)  s
 s
b) 3.41 mm
Explanation:
a)
We take the speed of light, c =  m/s and the refractive index of glass as 1.517.
 m/s and the refractive index of glass as 1.517.
Speed = distance/time
Time = distance/speed 
Refractive index, n = speed of light in vacuum / speed of light in medium






b)
We take the refractive index of water as 1.333.
Speed in water = speed in vacuum / refractive index of water
Distance = speed * time



d = 3.41 mm
