Do I use the image distance from one mirror as the object distance from the next mirror?
(I meant lens, not mirror)
DIVERGING LENS:
ho = 2 cm
do = 20 cm
f = -10 cm
di = -6.67 cm
hi = 0.67 cm
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
CONVERGING LENS:
do = 6.67 (diverging lens's di)
ho = 0.67 (diverging lens's hi)
f = 6 cm
di = 60 cm
hi = 6 cm
Am I doing it right?
Wait, since the image distance is negative for the diverging lens, that means it's 6.67 cm in FRONT of the lens, so it's 6 cm PLUS 6.67 for the object distance from the converging lens, right?
To determine whether you should use the image distance from one mirror as the object distance for the next mirror, we need to consider the configuration of the mirrors and the type of optical system being used.
In the given image, it appears we have a system with two mirrors placed in a "folded" configuration. The light rays are reflected from one mirror to the next in order to create an image.
In this type of configuration, the image formed by the first mirror can indeed serve as the object for the second mirror. However, you need to consider the sign conventions and the direction of the light rays.
Here are a few things to keep in mind:
1. Sign conventions: When working with mirrors, the conventions for distances are as follows:
- Object distance (do) is positive on the same side as the incident light.
- Image distance (di) is positive on the opposite side of the incident light.
- Focal length (f) is positive for concave mirrors and negative for convex mirrors.
2. Direction of light rays: Light rays travel in straight lines from the object to the mirror and then to the image.
With these considerations in mind, if the image formed by the first mirror is real and on the opposite side of the incident light, you can consider its image distance (di) as the object distance (do) for the second mirror. However, remember that you need to assign the appropriate signs to the distances and focal lengths based on the mirror type and location.
It is important to note that without more information or specific details about the mirror configuration and optical system, it is difficult to provide a more precise answer.
