CT scanners do not detect details smaller than about 0.5 mm. Is this limitation due to the wavelength of x rays? Explain.
The Critical Angle Derivation
So the critical angle is defined as the angle of incidence that provides an angle of refraction of 90degrees. Make particular note that the critical angle is an angle of incidence value. For the waterair boundary, the critical angle is 48.6degrees.
