Conclusion:After studying the laws of reflection and refraction, we verified that the angle of incidence and the angle of reflection on a given reflective surface are equal that the focallength is half of the radius of curvature of the mirror’s surface (R = 2f or f = R/2), and that refraction occurs when light reaches a boundary between two transparent mediums of differing densities. We also verified that the refractive index of water is about 1.33, which means that it takes light about 33% longer to travel through water than air. In addition, we saw that the critical angle is directly related to total internal reflection, which will only occur if light passes from a medium of greater refractive index into one of a lesser refractive index if the angle of incidence is greater than the critical angle.The critical angle for any boundary can be predicted using Snell’s law or by conducting an experiment.. The phenomena of critical angles is apparent when observing the brilliance and sparkle of a strategically-cut diamond. The critical angle for a diamond-air boundary is so small that light is essentially “trapped” inside of the diamond for a brief moment, leading to total internal reflection numerous times before the light is refracted out of the stone. Optics is a vital branch of physics due to its endless applications. Anything that manipulates the direction or capturing of light involves an optical principle, such as fiber optics, telescopes/microscopes, lasers, cameras, etc.

Answer 2

Conclusion of reflection of light is given below:

• Reflected ray meets incident ray as well as the normal ray at one point, which is called point of incidence.
• All the three rays- incident ray, reflected ray, as well as the normal lie in one plane only.
• The angle of incidence will always have the same value as that of the angle of reflection.

Conclusion of reflection of light is commonly known as laws of reflection of light.

Conclusion of light is derived by-

• The conclusion of light is derived by performing an experiment with the help of a plane mirror.
• The image formed by the plane mirror is studied and pins are fixed to denote the incident ray and reflected ray.
• Normal is drawn at the point where reflected ray and incident ray intersects with each other.
• Observations are made and the conclusion given above are thus derived.
