The equation connecting s, p, and f for a simple lens can be employed for spherical mirrors, too. A concave mirror with a focal length of
5 cm
forms an image of a small object placed
15 cm
in front of the mirror. Where will this image be located? (For spherical mirrors, positive p means the image is on the same side of the mirror as the object.)
a hyperbolic mirror used in some telescopes has the property that a light ray directed at the focus will be reflected to the other focus. if the focus of the hyperbolic mirror has coordinates (12,0). find the vertex of the mirror if its mount at the top edge of the mirror has coordinates (12,12)
(a) What is meant by the focal length of a converging lens?
(b) An object is placed in front of a converging lens. A real image is formed, as shown in Fig. 7.1.
The converging lens is not shown.
(i) Explain what is meant by a real image.
(ii) Rays of light from point A on the object form point B on the image.
On Fig. 7.1, draw

this position,
2. a ray to find the position of a principal focus of the lens, marking this position F,
3. a third possible ray from A to B.

- A reflecting mirror is made in the shape of the surface of revolution generated by revolving the curve y(x) about the x-axis. In order that light rays emitted from a point source at the origin are reflected back parallel to the x-axis, the curve y(x) must obey Y 2p 1– p2' dy where P = dæ . By solving this equation for x find the curve y(x). [Hint: Make y the subject of the formula and differentiate both sides to get a first order equation in p. Then solve that equation and substitute your solution into the original equation.]arrow_forwardAn object of height 1 cm is placed 2.5 cm in front of a concave mirror of focal length of 3 cm.

- The equation connecting s, p, and f for a simple lens can be employed for spherical mirrors, too. A concave mirror with a focal length of 2 cm forms an image of a small object placed 10 cm in front of the mirror. If the mirror is used to form an image of the same object now located 18 cm in front of the mirror, what would the new image position be? (For spherical mirrors, positive p means the image is on the same side of the mirror as the object.) The image will be cm ---Select--- v the mirror.
