It is an electromagnetic radiation within the portion of EM-Spectrum that can be seen by the human eye. Light Scatters in all directions as it goes away from its source. Light has both particles as well as wave nature.
Reflection of light is the phenomenon associated with bending of light rays. It is the process in which light rays are sent back after falling on a surface of an object.
Refraction of light is the bending of light when it passes through one medium to another.
It is the slight bending of the light when it passes through the edge of an object.
Interference is the phenomenon in which two primary waves are superimposed to generate new secondary waves. It is based on Huygen’s Principle.
Dispersion of light is the phenomenon of splitting up of white light into its different components.
It is the alignment of light waves in a particular plane. The instrument used for polarization is known as polarizer.
Scattering of light is the phenomenon of light by which light gets scattered in different directions as it moves away from its source and it is deviated from its straight path.
There are many materials that show different behaviour towards light. Some materials absorb the light falled on them and some of them refract the light, some absorb particular colors of light. Many materials store up light energy and reflect it back after some time. Some materials may generate electric energy after absorbing light.
Question 1: Can light bend around corners?
Answer: Yes, Light bends around corners and the phenomenon associated with it is called diffraction of light.
Question 2: Is a light particle or a wave?
Answer: Light has both characteristics. It shows particles as well as wave nature.
Question 3: Anything which gives out light rays is known as____.
Answer: Object

Light always travels in a straight line. They travel like electromagnetic waves. It also holds the particle nature.
The basic working principle of light involves the scattering of light, reflection of light, and refraction of light.
Light enters our eye by the clear outer layer present at the front of our eye. That clear outer layer is called the cornea.
The reflection of light from a plane surface occurs by the angle, which is the same as the angle of incident. And, the reflection of light from a rough surface occurs by scattering the light in many directions. In both cases, incidence and reflected light remain in the same medium.
Light is a form of electromagnetic radiation, which has kinetic energy, This energy can be used to generate electricity by using a photocell.
Light is a form of electromagnetic radiation, it holds both wave and particular nature. It has kinetic energy. Light helps us to see, and it also keeps our earth warm.
Following are some properties of light.
Reflection: Light reflects through the surface and remains in the same medium of incidence.
Refraction: Light travels to another medium after the incidence.
Dispersion: Splitting of light in its constitutional colors.
Differentiation: Bending of light from the corner.
Interference: Suoperimposition of light waves.
