A magnifying lens has a focal length of 100 mm. An object whose size is 16 mm is placed at some distance from the lens so that an image is formed at a distance of 25 cm in front of the lens? a) What is the distance between the object and the lens? Where should the object be placed and the lens?

A convex lens has focal length of 30cm. Calculate at what distance should the object be placed from the lens so that it forms at 60 cm on the other side of the lens ? Find the magnification produced by the lens in this case.

I couldn't find any videos and few articles for how exactly they work, so I argued with GPT for a while and now I'm even more confused.

Focal length of the concave lens is 40 cm. An object is kept at a distance 40 cm from the lens. What will be the location and magnification of image formed?

Edmund Optics Tech Tools Equations ; Focal Length Calculator, equation 1. (1) ; Focal Length Calculator, equation 2. (2) ; Focal Length Calculator, equation 3. (3).

GPT eventually claimed that the camera sensor simply needs to be as large as the aperture. But that doesn't make sense right? I thought telecentric lenses could snap onto any camera with any sensor.

4. Finding u: Now, take the reciprocal to find u: u=304=7.5 cm Since the object distance is measured from the lens, it will be: u=−7.5 cm(negative sign indicates the object is on the same side as the incoming light)

1. Use the Magnification Formula: The magnification (M) is given by: M=h′h=−vu Where h′ is the height of the image and h is the height of the object.

Given:- Focal length (f) = 10 cm (positive for a convex lens)- Image distance (v) = -30 cm (negative because the image is on the same side as the object for a real image)
