Image Formation by a Plane Mirror
- Virtual, erect and at the same distance from the object.
- Virtual, inverted and at a distance two times as the object.
- Real, erect and at the same distance from the object.
- Real, inverted and at a distance half as the object.
Which of the following pairs of angle will be equal in the given figure. Given ∠2 = 30∘
∠1 = ∠4
both (b) and (c)
∠2 = ∠3
In a plane mirror, the middle surface is covered with a dark paper. How many images of yourself will you see in the mirror if earlier you could see only 1 image?
A person suffering from myopia is holding a mirror at 100 cm from his face. But he cannot look at it’s image. So he moves the mirror towards him by 40 cm. Find the distance by which his image moves?
A ray of light is incident on the plane mirror at a angle as shown in the figure, what is the angle made by the reflected ray to the normal?
None of these
If you are standing between 2 mirrors and you see 3 images of yourself then, find out the angle at which these mirrors are inclined to each other?
If a plane mirror is moved by a velocity 10 msec towards the object. Find out the velocity of the image and its direction?
10 m/s, towards the mirror.
10 m/s, away from the mirror.
20 m/s, away from the mirror.
20 m/s, towards the mirror.
- 10 ms−1, away from mirror
- 10 ms−1, towards the mirror
- 2 ms−1, away from mirror
- 5 ms−1, towards the mirror
If you are standing between 2 plane mirrors, inclined to each other at 60°. Then find number of images that you can see of yourself?
If an object moves 5 msec towards the mirror. And the mirror also moves 5 msec towards the object. Then find out velocity by which image will move?
5 m/s, towards the mirror
10 m/s, towards the mirror
25 m/s, towards the mirror
15 m/s, towards the mirror
