The author presents an elementary theory of image formation by a concave spherical mirror, elaborated for arbitrary angles of incidence and wide beams of rays. The image formation of a point source is either real, virtual or mixed according to the position of the source with respect to the ...
A third type of image is formed by a diverging or concave lens. Try looking through eyeglasses meant to correct nearsightedness. (See Figure 12.) You will see an image that is upright but smaller than the object. This means that the magnification is positive but less than 1. The ray d...
Consider the situation shown in Figure 4, concave spherical mirror reflection, in which an object is placed farther from a concave (converging) mirror than its focal length. That is,fis positive anddo>f, so that we may expect an image similar to the case 1 real image formed by a convergi...
To solve the question, "The image formed by a plane mirror is upright," we can follow these steps:Step 1: Understand the characteristics of a plane mirror A plane mirror is a flat reflective surface that reflects light accordin
Why does an image not form in a concave mirror when an object is placed at its focal point? The passenger side mirror is a convex mirror, making objects appear closer than they actually are. Is this right? Explain. ...
A 2.25 cm high object is placed 3.0 cm in front of a concave mirror. If the image is 5.0 cm high and virtual, what is the focal length of the mirror? A concave mirror has a focal length of 38 cm. The image formed by this mirror i...
The image formed by a convex mirror is always behind the mirror. It means the image that forms by a plane mirror is a virtual image. So it is not possible to have a real image of a real object formed by a convex mirror. Step 3: In the case of a concave mirror, ...
When an object is kept at a distance of 30cm from a concave mirror, the image is formed at a distance of 10 cm. if the object is moved with a speed of 9 cm/s, find the speed (in cm/s) with which image moves. View Solution An object is placed at 6 cm distance in front of...

4. What is the difference between a real image and a virtual image in a concave mirror? A real image is formed when light rays actually converge at a point to create an image. This type of image can be projected onto a screen and is always inverted. A virtual image, on the other ha...
