WebIts stated that light travels in straight line,but owing to the huge number of optical instruments we use today,namely lenses,mirrors,prisms,etc. we are able to change the direction of the light's motion,deviate it from its actual path and hence'bend'it.Here I would also suggest that like in geometry we know that circle is a combination of a ... WebJul 24, 2024 · Light is a type of electromagnetic radiation that travels in a straight line. It is made up of tiny particles called photons, which are emitted by atoms when they are excited. When these photons hit something, they cause it to emit light. This is how we see things in the world around us. Light travels at a speed of about 300,000 kilometers per ...

WebIt does not move in straight lines or constant velocity in accelerating reference frames or in non homogeneous media. The fact that the speed of light is independent of the … Webthe light slows down going into a denser substance, and the ray bends towards the normal the light speeds up going into a less dense substance, and the ray bends away from the normal WebThe Direction of Bending. Refraction is the bending of the path of a light wave as it passes from one material into another material. The refraction occurs at the boundary and is caused by a change in the speed of the light wave upon crossing the boundary. The tendency of a ray of light to bend one direction or another is dependent upon whether ... help ox
