Answer:
b
Step-by-step explanation:
The speed of the light ray in the corn oil is 2.04×10⁸ m/s
Speed of light
This is the speed at which light travels in space. It has a constant value of 3×10⁸ m/s
How to determine the speed of light in corn oil
Refraction index (n) = 1.47
Speed of light in space (c) = 3×10⁸ m/s
Speed of light in corn oil (v) =?
n = c / v
1.47 = 3×10⁸ / v
Cross multiply
1.47 × v = 3×10⁸
Divide both side by 1.47
v = 3×10⁸ / 1.47
v = 2.04×10⁸ m/s
Thus, the speed of light in corn oil is 2.04×10⁸ m/s
