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
A
2.50 cm
B
6.67 cm
C
7.50 cm
D
7.63 cm

Correct Option: B
Refraction index, n = (real depth)/apparent depth
1.5 = (10)/X
X = (10)/1.5 = 6.67 cm
