A convex lens produces a real, inverted image of an object that is magnified 3.0 times when the object is 28 cm from the lens.

(a)What is the image distance of the lens?

(b) What is the focal length of the lens?

(2)An object placed 30 cm in front of a converging lens forms an image 11 cm behind the lens

(a)What are the focal length of the lens?

(b)What are the lateral magnification of the image?

(3)When an object is placed at 2.3 m in front of a diverging lens, a virtual image is formed at 30 cm in front of the lens.

(a)What are the focal length of the lens?

(b)What are the lateral magnification of the image?

(4)Design the lens in a single-lens slide projector that will form a sharp image on a screen 4.6 m away with the transparent slides 5.8 cm from the lens.

If the object on a slide is 1.5 cm tall, how tall will the image on the screen be?’

The image is: inverted or upright??
