Mirage is an optical illusion which can be explained based on which of the following phenomena of light?
Total Internal Reflection
A mirage is an optical illusion explained by Total Internal Reflection of light as it passes through layers of air with varying densities near a hot surface.
Interference, diffraction and the photoelectric effect are other optical or quantum phenomena, not the one responsible for mirages.
Hence, 'Total Internal Reflection' is the correct answer.
Modern telecommunication systems use optical fibres to transmit data efficiently. Which optical phenomenon enables this high-speed data transmission?
Which of the following properties is responsible for the bending of light when it moves from air into water?
Two convex lenses have focal lengths of 50 cm and 25 cm, respectively. If these two lenses are placed in contact, then the net power of this combination will be equal to
The refractive index of crown glass is close to 3/2. If the speed of light in air is c, then the speed of light in the crown glass will be close to
Tyndall effect is a phenomenon of
