If an object is placed on the focal point in front of a convex lens, what type of image will be formed?

An object of height 11 cm is placed 44 cm in front of a converging lens with a focal length of 24 cm. What's the height of the image?

An object is placed 40 cm in front of a converging lens that has a 60-cm focal length. Where will the image be formed? Select answer from the options below 24 cm in front of the lens    120 cm in front of the lens  None of the choices are correct. 120 cm behind the lens 24 cm behind the lens

You place an object 17.4 cm in front of a diverging lens which has a focal length with a magnitude of 12.6 cm. Determine how far in front of the lens the object should be placed in order to produce an image that is reduced by a factor of 2.85.

An object is placed 40cm in front of a convex lens of focal length 30cm. A plane mirror is placed 60cm behind the convex lens. Where is the final image formed by the system ?

For a thin lens situaiton, you have detemined the image distance is negative. Which of the following must be true?     the image is real, it is on the opposite side as the object     the image is virtual, it is on the same side as the object     the image is real, it is on the same side as the object     the image is virtual, it is on the opposite side as the object

An object is placed 40 cm from a converging lens with a focal length of 20 cm. The image formed by this lens becomes the object for a second diverging lens with a focal length of −15 cm. The distance between the two lenses is 50 cm. Calculate the final image distance formed by this two-lens system. Draw a diagram of the optical system.

A person is nearsighted and can clearly focus on objects that are no farther than 3.3 m away from her eyes. She borrows a friend's glasses but the borrowed glasses make things worse; that is, the person can now focus only on objects that are within 2.55 m away. What is the focal length of the borrowed glasses?

Can someone draw a mirror ray diagram for me, using the given values? Then label the parts?

Consider a converging lens that has a focal length (f). Which one of these is correct about the image when the object is placed in front of the lens at a distance of (3f/2 )? (Choices Below) __ The image is real, erect, and has the same size as the object__ The image is real, inverted, and magnified__ The image is virtual, inverted, and magnified__ The image is real, inverted, and diminished__ The image is real, erect, and diminished__ The image is real, erect, and magnified
