Question

“Rohit was standing outside his house. He wants to see image of his house in mirror. He

takes some mirror and finally he achieved his goal.

(a) Name the types of mirror that was taken by Rohit. 1

(b) Draw a ray diagram when an object is between pole and infinity of convex mirror. 1

(c) Define concave and convex mirror. 1

(d) Write the relation between radius of curvature and focal length of mirror. 1

(e) Define the magnification of mirror.​

Answer 1

Answer:

plane mirror

If the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Image. Concave mirrors can form inverted and real images and also virtual and erect images. Convex mirrors form virtual and erect images

The distance from the pole to the center of curvature is called (no surprise, I hope) the radius of curvature (r). The distance from the pole to the focal point is called the focal length (f). The focal length of a spherical mirror is then approximately half its radius of curvature.

The magnification, m, is defined as the ratio of the image height to the object height, which is closely related to the ratio of the image distance to the object distance: A magnification of 1 (plus or minus) means that the image is the same size as the object.
