What does a lense camera do to switch from a far away object to a close one?

Moves lense and film farther apart

Myopia

Near sighted, far point it too short, correct via diverging lense

Hyperopia

far sighted, near point too far out, correct with converging lense

A greater curverature for a lense makes the focal point

shorter

If N is greater, f is

shorter

How is P related to f

f = 1/P

A diverging lense gives an image that is

virtual and smaller

What lense can give real images?

Converging

What does a converging lense OUTSIDE f make the image

real and smaller

What type of image does a converging lense with an object between 1f and 2f give you?

real and bigger

What type of image does a converging lense INSIDE focal point give you

virtual and big
