Final answer:
When an object is reflected in a flat mirror, the image formed is virtual, upright, and the same size as the object. To find the final image through a lens and mirror, draw the incident rays to the lens, find the intermediate image, then draw the reflected rays to the mirror.
Step-by-step explanation:
Reflection in a Flat Mirror:
When an object is reflected in a flat mirror, the image formed is virtual, upright, and the same size as the object. The image is located behind the mirror at the same distance as the object is in front of the mirror.
Ray Diagram:
To draw the rays and find the final image through a lens and mirror, follow these steps:
- Draw the incident rays from the object to the lens, according to the given directions.
- Using the lens alone, find the intermediate image of the object. Treat the intermediate image as the new object.
- Draw the reflected rays from the intermediate image to the mirror and extend them backward behind the mirror to find the final image.
Example:
If a parallel incident ray strikes the lens and converges towards its focal point, it will reflect from the mirror and diverge away from the focal point behind the mirror, forming the final reflected ray. Repeat this process for all the incident rays to locate the final image.
