Question

explain total internal reflection of light ​

Answer 1

Explanation:

Total Internal Reflection (TIR) is the phenomenon that makes the water-to-air surface in a fish-tank look like a perfectly silvered mirror when viewed from below the water level (Fig. 1). Technically, TIR is the total reflection of a wave incident at a sufficiently oblique angle on the interface between two media, of which the second ("external") medium is transparent to such waves but has a higher wave velocity than the first ("internal") medium. TIR occurs not only with electromagnetic waves such as light waves and microwaves, but also with other types of waves, including sound and water waves. In the case of a narrow train of waves, such as a laser beam, we tend to speak of the total internal reflection of a "ray"..

Mark as brainliest plz..

Answer 2

Answer:

if the angle of incidence is greater than critical angle , the light Ray is reflected into denser medium at interface. This phenomenon is known as total internal reflection
