With help of NCERT Solutions Class 10th Study material by Extramarks, you can clear your concepts for more topics like Sources of Energy, Acids, Bases, and Salts. These mediums cause the light to ‘refract’ and that slows the light down. Light doesn’t travel as fast when it has to pass through mediums that are different, such as air, water or glass. When it goes back into the less dense medium (with a lower refractive index), it will bend back through the same angle as when it came in (if the surface at exit is parallel to the surface at entry). 
As light goes into a medium which is denser, the light ray will ‘bend’ toward the normal. Light travels in a vacuum at 300,000 km per second (186,000 miles per second). There are numerous phenomena based on refraction like how the object bends when partially submerged in water, or the mirages seen in a hot desert. An astronomical reflecting telescope that uses a parabolic mirror and a plane mirror are also examples of reflection. The Microscope is another example as utilizes a mirror as well. The mirror (rearview mirror in vehicles) is a classic example of the phenomenon of reflection. The angle of incidence is not equal to the angle of reflection.Īs we have seen the difference between reflection and refraction, let us now discuss some Examples of Reflection and Refraction. The angle of incidence is equal to the angle of reflection. The light waves go through the surface while concurrently changing from medium to medium. Reflection considers the light waves, bouncing from the plane and changing direction. The light that enters the medium travels from one medium to another. The light that enters the medium comes back in the same direction. Refraction is the process of light shifting when it passes through a medium resulting in the bending of the light. reflection of light is when it strikes the plane’s medium (there is no penetration of the light). There is a simple definition for reflection. This phenomenon of reflection is usually noticed in mirrors or other shiny surfaces. Let us now discuss what are the important difference between reflection and refraction in tabular form: Reflection vs Refraction The incident ray, the refracted ray, and normal ray at the interface of any two-given medium, all lie in the same plane.” “The ratio of the sine of the angle of incidence and the sine of the angle of refraction is constant in any two-given medium. Irregular reflection: Irregular reflection also called diffuse reflection occurs when the light beam strikes a rough surface and reflects light in numerous directions. Regular reflection: Regular reflection also called specular reflection occurs when the light beams strike a regular, polished, and smooth plane. The ray of incidence, the ray of reflection, and the normal drawn at the point of incidence, to the mirror, occurs on the same plane.” “The angle of incidence is identical to the angle of reflection. Reflection of light modifies the direction of the beam of light as it strikes the plane so the ray reverts to the medium in which it first got produced. 
Simply put, reflection means “the rebounding of light, sound, heat, or another object back to the source, without absorbing it.”
Lot students wonder what is the difference between reflection and refraction so here is a detailed blog to help you understand it. Reflection and Refraction are the two major phenomena related to the propagation of beam of light. When light passes through a different medium, two varied phenomena happen: Reflection and Refraction. When light reflects from a surface or travels from one medium (transparent) to another or via a medium then it changes direction.
