10Critical angle is the angle of incidence at which the refracted ray is along the boundary.
Critical angle occurs when light travels from rarer to denser medium.
Total internal reflection occurs only if i > critical angle.
Water has a smaller critical angle than glass.
Diamond has a critical angle of approximately 24°.
Alcohol has a larger critical angle than glycerin.
Light is refracted at the critical angle at 90° to the normal.
Critical angle depends on the wavelength of light.
Total internal reflection can occur in air → water interface.
The critical angle for kerosene oil is 44°.
