Light is electromagnetic radiation that shows properties of both waves and particles. Light is a form of energy. Light also keeps the Earth warm. Light exists in tiny energy packets called photons.

Answer: Light is a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. Light is a kind of kinetic energy Which enables the human eye to see or make things visible. Light energy is a form of electromagnetic radiation that can be seen by the human eye.

Light: (i) Light is a form of energy, which includes the sensation of vision in our eyes and make us able to see various things present in our surrounding. (ii) When light falls on an object, some part of light is reflected back to our eyes.

Light is a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. When an object’s atoms get heated up, it results in the production of photons and this is how photons are produced. The electrons find excitement from the heat and result in earning extra energy.

Light has the usual attributes of waves, namely frequency, wavelength and speed.

A ray of light is incident on a totally reflecting surface (mirror) at a certain point. If we draw a line which is perpendicular to the reflecting surface at the point of incidence, this line is called the normal. As such it is an imaginary line perpendicular to the surface reflecting the light.

Answer: Normal is a line drawn perpendicular to the surface of mirror from point the point where incident ray meets the surface of the mirror. The angle of incidence is the angle the incident ray makes with the normal drawn at the point of incidence of the incident ray on he surface of the mirror.

The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.

A Small Mirror Mirrors are great to reflect light or redirect sun rays. Remember that white sheets and walls diffuse as well as reflect light, they spread light out. A mirror just reflects, so it can be used to create small pools of more direct light on subject objects.

Rays of light reflect, or bounce off, objects just like a ball bounces on the ground. This reflection of light is what enables us to see everything around us. Take a look out your window: you see everything in the natural world (that doesn’t produce its own light) because it reflects the light of the Sun .

The bottom line is: without light, there would be no sight. The visual ability of humans and other animals is the result of the complex interaction of light, eyes and brain. We are able to see because light from an object can move through space and reach our eyes.
