Question
Find the critical angle for liquid-air interface if the refractive index of the liquid is 2.30°45°60°25°
Solution
The critical angle (c) can be found using the formula:
c = arcsin(1/n)
where: n is the refractive index of the medium from which the light is coming.
Given that the refractive index (n) of the liquid is 2.30, we can substitute this value into the formula:
c = arcsin(1/2.30)
Now, calculate the arcsin(1/2.30) using a scientific calculator to get the critical angle in degrees.
