![]() Light- Reflection, Refraction, Dispersion and Scattering 2-The refraction (ii) The 30% radiations of total light energy exposed to the earth are reflected back to space regulates the temperature in the earth, this phenomenon of reflection of light keeps us away from the excess temperature in the earth. When light rays fall on a rough surface then these are reflected in all directions and rules of reflection are not followed, it is called diffused reflection.Īpplication of reflection of light- (i) We become capable to see everything due to the reflection of light. Light- Reflection, Refraction, Dispersion and Scattering Diffused reflection (2) When light rays fall on a smooth surface of an object, the angle between the incident ray and normal known as the incident angle is always equal to the angle between normal and reflected angle known as the reflected angle. (1) When light rays fall on a smooth surface of an object, the incident ray, reflected ray and the normal to the surface on the incident point all lies in the same plane When light rays fall on the surface of an object, the surface of the object sends back light rays by a certain angle to another direction, in other words, the phenomenon that light ray bounces off an object is known as reflection. it can be said that the Sun is the largest source of energy on the earth, it is because of the virtue of light reflection we use microscope, telescope, radar, etc. The sun is the largest source of light to us. We see everything in this world due to the presence of light, light rays fall on the object and then send back to our eyes and image of the object formed on the retina of our eyes and thus we become capable to see the object.

In modern physics, the light is supposed as a wave due to the characteristics of reflection, refraction, diffraction, scattering, and interference in contrast to the concept of light as particles due to its phenomenon of dispersion and the photoelectric effect, therefore it is supposed that light has dual nature,it behaves as particles and as a wave. ![]() In the 20 th century, the greatest scientist Einstein concluded to the fact from Hertz’s discovery of the photoelectric effect of light that light is made of the photon. Newton in 17 th century also embedded one more concept when he introduced that light is made of particles, this theory was opposed by Huygens and advocates the theory of light as a wave because of the light’s characteristic of reflection and refraction, later Maxwell introduces that light is an electromagnetic wave. Initially, the scientist observes the varying size of the moon, the position of the stars and visual perceptions. The observations of astronomy have led the theory of light in modern optics. The reflection, diffusion, and vision were summarized by Euclid (300 -275 BC) in his book Optics. The concept that light is a wave had been discovered in ancient Greece in 5 BC to 3 BC. The branch of physics in which the characteristics of light are studied is known as Optics. Refraction of light is the deviation of a light ray from its own way and dispersion is splitting up of light ray into seven colors, when light ray enters the fluid, the particles of medium spread the light around them, this phenomenon of light is known as scattering. Light, Reflection, Refraction, Dispersion, and Scattering are the properties of light, reflection of light is bouncing back of the light ray when it incidents on an opaque surface.
