The Shiny Outer Surface of a Hollow Sphere of Aluminium of Radius 50 Cm is to Be Used as a Mirror: Which Type of Spherical Mirror Will It Provide? - Science

A student used a device (X) to obtain/focus the image of a well illuminated distant building on a screen (S) as shown below in the diagram. Select the correct statement about the device (X).

Define the following term in the context of spherical mirrors:- Principal focus

Give one use each of a concave and a convex mirror.

The letter F is placed in front of a plane mirror:

What is the name of the phenomenon involved?

A ray of light travels from a denser medium to a rarer medium. How will it bend?

Name the kind of mirror used to obtain
(a) a real and enlarged image
(b) a virtual and enlarged image
(c) a real and diminished image, and
(d) a virtual and diminished image.

A student obtained on a screen the sharp image of a candle flame placed at the farther end of laboratory table using a concave mirror. For getting better value of focal length of the mirror, the teacher suggested to him to focus the sun. What should the student do?
(A) Should move the mirror away from the screen.
(B) Should move the mirror towards the screen.
(C) Should move the mirror and screen both towards the sun.
(D) Should move only the screen towards the sun.

State the position of object for which the image formed by a concave mirror is of same size.

What type of mirror can be used to obtain a real image of an object?

Draw a ray diagram to show the formation of image of an object kept in front of a convex mirror. State three characteristics of the image.

At what distance from a concave mirror of focal length 25 cm should an object be placed so that the size of image is equal to the size of the object.

An object is placed at 4 cm distance in front of a concave mirror of radius of curvature 24 cm. Find the position of image. Is the image magnified?

State three characteristics of the image formed by a convex mirror.

The boxes in figure (a, b, c) represent mirrors; insert a mirror which will reflect the incident ray as shown in the diagram.

Complete the following diagrams shown in the following figures by drawing the reflected rays.

An object is placed in front of a concave mirror as shown in the following figure. By scale drawing, find the nature of the image. Given f = 10 cm, v = 30 cm.

The diagram below shows the parallel rays incident on a convex mirror. C is the centre of the curvature of the mirror. By drawing the paths of the reflected rays, label the focus F and hence find the focal length of the mirror.
