WebWhen the angle of refraction is equal to 90o, the angle of incidence is called the critical angle. If the angle of incidence is greater than the critical angle (i.e. greater than 90o ), no light passes through the medium - it is totally internally reflected. You can find the critical angle, C, of a material using the following equation: WebTherefore, the angle of incidence (and reflection) is 90° – 25° = 65° Step 2: Draw the refracted angle at the glass-air boundary. At the glass-air boundary, the light ray refracts away from the normal; Due to the reflection, the light rays are symmetrical to the other side; Step 3: Calculate the critical angle
