Solution

Yes, we can obtain the image formed by a plane mirror on a screen. Here are the steps to explain why:

  1. When an object is placed in front of a plane mirror, light rays from the object hit the mirror's surface and reflect off it.

  2. According to the law of reflection, the angle of incidence (the angle between the incident ray and the normal to the mirror's surface) is equal to the angle of reflection (the angle between the reflected ray and the normal).

  3. The reflected rays form an image behind the mirror. This image is virtual, meaning it cannot be projected onto a screen or captured on a surface.

  4. However, we can use a screen or any other flat surface to observe the image formed by the mirror. By positioning the screen at the location where the virtual image appears to be, we can see the image.

  5. The image formed by a plane mirror is laterally inverted, meaning it appears flipped horizontally compared to the object. For example, if the object has the letter "A" on it, the image will show the letter "A" flipped horizontally.

  6. The image formed by a plane mirror is also the same size as the object. This is because the distance between the object and the mirror is equal to the distance between the mirror and the image.

In conclusion, while the image formed by a plane mirror is virtual and cannot be projected onto a screen, we can observe the image by placing a screen at the location where the virtual image appears.
