In finding the index of refraction, we use this formula n= c/v

where n is the index of refraction
c is velocity of light in vacuum, this is constant and is equivalent to 3x10^8 m/s
v is the velocity of light in a particular medium, in here we use 1.97x10^8 m/s

Using the formula,

n = (3x10^8 m/s) / (1.9x10^8 m/s)
n = 1.52284264
n = 1.52

Hope this helps. :)

n = c / v
n = index of refractionc = velocity of light in vacuum = 3x10^8 m/sv = 1.97x10^8 m/s

n = (3x10^8 m/s) / (1.9x10^8 m/s)n = 1.52

the index of the liquid is 1.52
