Answers
Answer:
light or visible light is electro magnetic radiation
Answer:
1)Light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye.
2)When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light.
Different types of reflection of light are briefly discussed below:
Regular reflection is also known as specular reflection
Diffused reflection
Multiple reflection
3)Following are the laws of reflection:
a)The incident ray, the reflected ray and the normal to the surface of the mirror all lie in the same plane.
b)The angle of incidence is equal to the angle of reflection.
4)Regular Reflection:
1. Reflection from a polished surface is called regular reflection.
2. parallel rays remain parallel after reflection.
Irregular Reflection:
1. Reflection from a rough surface is called diffuse reflection.
2. Parallel rays do not remain parallel after reflection.
5)The light rays propagate in a straight line.When any object comes in its path of propagation, it bends back or reflects back alter striking the object. The reflected rays come to our eyes and we see the objects around us.
