An object is embedded in a block of ice, 10 cm below the plane surface. if the refractive index of the ice is 1.50, the apparent depth below the surface is?
- 2.50 cm
-
6.67 cm
- 7.50 cm
- 7.63 cm
The correct answer is: B
Explanation
Refraction index, n = (real depth)/apparent depth
1.5 = (10)/X
X = (10)/1.5 = 6.67 cm
There is an explanation video available .
