A light ray travelling in medium a is refracted into medium b. The angle of incidence is 28.3° and the angle or refraction is 51.3°. Both angles are measured from the normal to the interface. If one keep increasing the angle of incidence until a critical angle beyond which the total internal reflection occurs, what is the critical angle (in degrees; remember to use the scientific notation of numbers)?

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
