- A small object is placed 25.0 cm to the left of a concave lens. A convex lens with a focal length of 12.0 cm is 30.0 cm to the right of the concave lens. The two-lens system forms a real inverted image 17.0 cm to the right of the convex lens. What is the focal length of the concave lens?Please help me with this question.A room in an amusement park funhouse has two flat mirrors on opposite walls, so that a person standing between the mirrors sees a "never-ending" series of reflections. A person stands 2.40 m from the mirror on the left wall and 5.50 m from the mirror on the right wall. What are the distances (in m), as measured from the person, for the first three images seen by the person in the left wall mirror? first image second image third image 2.40 X This is the image distance from the left mirror. Add this to the distance from the person to the mirror to get the total distance from the person to the image. m m m

- A tall tree is growing across a river from you. You would like to know the distance between yourself and the tree, as well as its height, but are unable to make the measurements directly. However, by using a mirror to form an image of the tree and then measuring the image distance and the image height, you can calculate the distance to the tree as well as its height. Suppose that this mirror produces an image of the sun, and the image is located 0.8278 m from the mirror. The same mirror is then used to produce an image of the tree. The image of the tree is 0.9219 m from the mirror. (a) How far away is the tree? (b) The image height of the tree has a magnitude of 0.13 m. How tall is the tree? (a) do = (b) ho= i iA plano-convex lens is one with a convex surface on one side and a flat surface on the other. Suppose a thin lens is made of glass with index of refraction 1.5.

- The focal points of a diverging lens are 25.0 cm from the lens. An object is placed 15.0 cm in front of the lens. What is the magnification of the image produced?Two plane mirrors make the angle a = 58.0° between them. A ray of light incident on one of the mirrors is reflected and it hits the second mirror, as shown in the figure. Determine the angle ẞ between the ray incident on the first mirror and the ray reflected off of the second mirror. B = BA technician places a 2.50 cm high crystal 2.50 cm in front of a concave mirror. This results in a 5.50 cm high virtual image of the crystal appearing as if behind the mirror.
