Question

Which of the following is a valid point in differentiating between an Image and an Object?
A). Image is the point of intersection of reflected/refracted rays while Object is the point of intersection of incident rays
B). The object is the point of intersection of reflected/refracted rays while Image is the point of intersection of incident rays
C). Image is the point of intersection of reflected rays while Object is the point of intersection of refracted rays
D). Image is the point of intersection of refracted rays while Object is the point of intersection of reflected rays

Answer 1

Generally, we already know that the object is a physical thing and able to touch and feel. But basically, the image is a graphical representation of a real object. Apart from that, there is some difference between an image and an object which we are going to discuss. We need to discuss the topics of reflection, refraction, incident rays, and point of intersection.

Complete step-by-step solution:
When we see any object, it emits light in all directions. In that way, the emitted light is entering into our eyes and so that the object is visible to our eyes. The image is formed by lenses and mirrors due to the refraction, reflection of light waves.
Reflection of light means when the incident ray strikes a medium or smooth surface, some of the incident light is reflected.
When the incident light passes through the transparent medium, a reflection occurs and also the light passes through the transparent medium. This Phenomenon of incident light passing from one medium to another medium is called Refraction.

In the concept of the converging lens, the object emits the incident light and the image formed by the refraction of incident light at the point of intersection. we came to know that the image is formed by the point of intersection of reflected/refracted rays.
The correct answer is option A) Image is the point of intersection of reflected/refracted rays while Object is the point of intersection of incident rays.

Note: The image is formed by the point of intersection of reflected/refracted rays of two types namely virtual image and real image. In-plane mirrors, virtual images are formed when the rays are diverging. In concave mirrors, the real image is formed. But in converging lenses, it produces both the real and virtual image.
