what is refrlaction and refraction. how does it fall from mirror?

Reflection: It is a phenomenon when light travelling in a medium falls on a surface and travels back in the same medium.
Example: When light travels from air and falls on a mirror, it turns back and travels back in air. This is reflection.
Refraction: It is a phenomenon when light travelling in a medium is incident on the boundary of the other medium, travels in the other medium.
In this, the speed of the light ray changes and hence it bends from its original path.
Example: When light is travelling in air and falls on a glass, then the light bends at the boundary of the air-glass interface and travels in glass. This is refraction.
From a mirror, only reflection occurs and refraction is not seen.

- when refraction does not cause when incident ray is normal to a interface
- An object 4 cm in size is placed 25 cm in a front of concave mirror of focal length 15 cm. find nature postion and size of the image draw the ray digram to show the formation of image in this case?
- CAN U SEND ME THE IMPORTANT FORMULAE IN LIGHT REFLECTION AND REFRACTION
- radius of curvature of a concave mirror is twenty five centimeter what is its focal length
- Draw the ray diagram when the object is kept between F1 and 2F1 of the convex lens. with the help of the diagram mention the position and nature of the image formed.
