![]() Students typically explore the mathematics of reflection during a lesson on graphing in the coordinate plane, within the. Such examples of reflection include mirrors, facial symmetry and projections of mountains or trees on the still waters of a lake. Some of the lenses used in real life that exhibit refraction include eye lens, microscope lens, telescope lens, spectacles lens, camera lens, etc. The concept of reflection in mathematics quantifies reflection in the natural and human world. Refraction of light is the change in the direction of light as it passes from one medium to another. If the medium has a smooth surface, then the angle of incidence is equal to the angle of reflection. The change in the nature and refractive index of the two media is responsible to cause the refraction of light radiations.Īll types of lenses are susceptible to displaying the natural phenomenon of refraction of light in real life. Reflection of light is when the light bounces off a medium. Sound travels through a medium like air or water as a mechanical wave. This happens as the stars are located in the outer space that does not have an environment whereas, the atmosphere of earth comprises a number of gases, water vapours, dust particles etc. Reflection of Sound may be described as the oscillations produced by a particle’s displacement or velocity conveyed in a medium with internal force, evoking auditory sensations. The light emitted by the stars gets directed towards the surface of the earth and gets refracted multiple times while travelling towards the ground. The process of the twinkling of stars is typically based on the refraction of light. Example 2: A ray of light strikes a plane surface at an angle of 50o. Hence, the angle of reflection will be 80o. The law of reflection states that the angle of reflection is always equal to the angle of incidence. Hence, the angle of incidence will be 80o. When a ray of light falls on the interface of the surface of the glass and air or any other medium, it tends to undergo a slight bend and exhibit refraction. If the light and surface are making an angle of 10o, then its normal angle would be 80o. Glass has a refractive index approximately equal to 1.0. ![]() Ice crystals or ice cubes are yet another objects present in our daily life that are capable of exhibiting the refraction process of light. The light radiation entering the glass prism tends to suffer a slight bend due to the change in the nature of the medium. PrismĪ glass prism is an instrument that is capable of demonstrating the refraction property of light in one of the easiest possible manners. There are a number of objects present around us that are capable of exhibiting refraction phenomena in real life.
