The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 3). There are far more occurrences of Physics / Reflection of Light at Plane surfaces. The branch of physics dealing with the properties and behaviour of light is called optics.

Total internal reflection refers to the complete reflection of a ray of light within an optically-denser medium from the surrounding surfaces of optically less dense media back into the denser medium.. Light ray travel from an optically denser medium to a less dense medium. The angle of incidence must be greater than a certain angle, called the critical angle. The effect of both reflection and refraction is to change the direction of the independent waves that are emitted by the point sources. The results of the rigorous calculations are identical to what is obtained from Newton's geometric optics (such as Snell's law of refraction), which was derived under a particle principle of light—although Newton's method is less elegant in its 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 Spherical Mirror Application - Light Reflection & Refraction, CBSE Class 10 Physics video for Class 10 is made by best teachers who have written some of the best books of Class 10.
