Answer:
2.17 x 10^8 m/s
Explanation:
Angle of incidence, i = 30 degree, refractive index of mineral oil, n = 1.38
Let r be the angle of refraction.
By use of Snell's law
n = Sin i / Sin r
Sin r = Sin i / n
Sin r = Sin 30 / 1.38
Sin r = 0.3623
r = 21.25 degree
Let the speed of light in oil be v.
By the definition of refractive index
n = c / v
Where c be the speed of light
v = c / n
v = ( 3 x 10^8) / 1.38
v = 2.17 x 10^8 m/s
