An object is 16.0cm to the left of a lens. The lens forms an image 36.0cm to the right of the lens. What can you conclude? A lens does not form an image on its own front surface. -The distance between the object and the lens is 16 cm. The distance between the image and the lens is 36cm.

What do you notice about these two distances?
What happens if we move this object to be 16m from a mirror with a focal length of 12m? Do you think that there will be an inversion? Why or why not? Try it! -What would happen to the image if we replaced the lens with a mirror? An object is 16.0cm to the left of a lens. The lens forms an image 36.0cm to the right of the lens. What can you conclude? A lens does not form an image on its own front surface, but instead it forms images at distances that are inversely proportional to their focal lengths from both surfaces (the rear and front).
The distance between the object and the lens is 16 cm. The distance between the image and t he lensis 36 cm . What do you notice about these two distances ? They’re proportional! Moving this object by half as many centimeters will result.
