The counterpart of an object produced by mirror , len , prism , etc after reflection or refraction is called image. It is of two types :
- Real image
- Virtual image
Each individual ray of light that strikes the mirror will reflect according to the law of reflection. Upon reflecting, the light will converge at a point. At the point where the light from the object converges, a replica, likeness or reproduction of the actual object is created. This replica is known as the image.An image may be defined as that point, where the light rays coming from an object meet or appears to meet after reflection or refraction. Explanation: In this definition the word 'object' may be defined as anything which gives out light rays.
An image may be defined as that point, where the light rays coming from an object meet or appears to meet after reflection or refraction. In this definition the word 'object' may be defined as anything which gives out light rays.Although a virtual image does not form a visible projection on a screen, it is no sense "imaginary", i.e., it has a definite position and size and can be "seen" or imaged by the eye, camera, or other optical instrument. A reduced virtual image if formed by a single negative lens regardless of the object position.
Each individual ray of light that strikes the mirror will reflect according to the law of reflection. Upon reflecting, the light will converge at a point. At the point where the light from the object converges, a replica, likeness or reproduction of the actual object is created. This replica is known as the image.Virtual image refers to the image which forms when the light rays appear to meet at definite point, after reflection from the mirror. An erect image is formed by the actual intersection of rays. ... It is an image in which directions are the same as those in the object.
An image can be seen in the mirror because the light reflected from an object falls on the mirror and it is reflected. So, light incident on any smooth shiny surface like a mirror bounces back into the same medium. This bouncing of light by any smooth surface is called reflection of light.
