Question
the refraction index of water is 1.33. calculate the critical angle
Solution
The critical angle can be calculated using the formula:
Critical Angle = sin^-1 (1 / Refractive Index)
Here, the refractive index of water is given as 1.33.
So,
Critical Angle = sin^-1 (1 / 1.33)
Now, use a calculator to find the inverse sine (sin^-1) of (1 / 1.33).
The result will be the critical angle in degrees.
