Students, welcome to our YouTube channel, Regispet. Today we discuss about real object, virtual object, real image and virtual image. That object is 2 type, one is real object and virtual object and image also 2 type, one is real image and another one is virtual image. So, students, we go to that topic one by one, first we go to real object, what is real object? When the incident rate comes from one point, when incident rate comes from one point or diverse from one point at that condition, that point object is called as real object. In case of real object, the incident rate are diverges. Now, go to the second one, virtual object. What is virtual object? When the incident rate are converged or appears to meet that point at that condition that object is called as virtual object. That means here we take two incident rate, this one is one incident rate and this one another incident rate, the two incident rate comes from infinity and here the surface of plane mirror at that condition here, reflection takes place. Okay. But if there is no plane mirror here, the two incident rate meet supposed to be meet at this point. Whenever there is no plane mirror here, the two incident rate supposed to meet at this point, here that object is produced and that object is said to be virtual object. Students in normal case or in our real life, virtual object is not exist. It just is substitute of real object. That means here we will consider a plane mirror, this one is the object here two incident rate comes from the object and falls on the surface of the plane mirror, you are reflected. Reflection takes place, this two are the two reflected rate, the two reflected rate. If you have to come from this point and here image is produced. If we take another mirror in front of this plane mirror, if we take another mirror in front of this plane mirror, then this image is as virtual object for the second mirror, this image is as virtual object which can use to create image for the second mirror. Okay. This one is dumps a camera and here the image is used or like virtual object and here this image is the virtual object for the second mirror. Now we go to real image and virtual image. So in case of real image, when the reflected ray converges, here the two reflected ray, diphages in this condition, here the two reflected ray converges or meet that point of intersection image is formed and that image is called as real image. When the reflected rays are converged or meet at one point, that image is called as real image and real image can be captured by wall and any screen. Next one is virtual image. When the reflected rays are diverged but appears to come from one point, that image is called as virtual image. Here the two incident rays falls on the surface of the plane mirror and reflection takes place. Here these two reflected ray diverges but appears to come from one point and that point of intersection image is reduced and that image is called as virtual image. So students, you remember just two things in case of real image always formed in front of the mirror and virtual image is formed behind the mirror. Virtual image is formed behind the mirror whereas real image is formed in front of the mirror. And real image is always inverted which real image is always irret and students you remember another sum to important point when the reflected ray are converged, when the reflected ray are converged. At that condition we got real image. Varaj, two reflected ray diverges but appears to come from one point at that condition that images of virtual image.
