You are trying to photograph a bird sitting on a tree branch, but a tall hedge is blocking your view. However, as the drawing shows, a plane mirror reflects light from the bird into your camera. For what distance must you set the focus of the camera lens in order to snap a sharp picture of the bird's image? 4.3 m -3.7 m-

Two lenses are separated by 50 cm. Lens 1 is convex and has a radius of curvature of magnitude 30 cm. Lens 2 is concave and has a radius of curvature of magnitude 40 cm and is located to the right of Lens 1. An object is located 20 cm to left of lens 1.   Find the location of the final image of the object. What is the magnification of the final image?

An object is 60.0 cm from a converging lens and the object is 1.00 cm tall. What is the poisition and height of the image if the focal length of the lens is 25.0 cm? The object is at 0.0233 cm and the height of the image will be 0.715 cm upright. The object is at 0.0233 cm and the height of the image will be 0.000388 cm inverted. The object is at 42.9 cm and the height of the image will be 0.000388 cm upright. The object is at 42.9 cm and the height of the image will be 0.715 cm inverted.

You are having trouble reading your cheat sheet during your physics exam because you wrote so small. You foresaw the problem, so you brought a small lens with you to the exam. You hold the lens 6 cm away from the page. The image you see is upright and 2.9 times the size of the writing on the page. where is image formed  Is the image real or virtual  what is the focal length of the lens  are you using a converting lens or a diverging lens

Some lenses are shaped with one flat side and one spherically-shaped side. This shape is designed to focus parallel light rays onto a single point. In a few sentences, explain how the spherical shape of the lens' surfaces causes parallel light rays to focus on a single point. (Assume the light is travelling through air into a lens with an index of refraction greater than that of air.) Focal length Focal point

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 fortuneteller looks through her crystal (n = 1.50) ball with a 4 cm radius centered at x = 0. An object at x = -16 cm is viewed from some positiondown the positive x-axis. Where does she see the image? Give the x-coordinate of the image position.   The answer is 9.6 cm, but I can't seem to get the right answer.

A man standing 1.54 m in front of a shaving mirror produces an inverted image 18.6 cm in front of it. How close to the mirror should he stand if he wants to form an upright image of his chin that is twice the chin's actual size? cm A contact lens is made of plastic with an index of refraction of 1.40. The lens has an outer radius of curvature of +1.92 cm and an inner radius of curvature of +2.47 cm. What is the focal length of the lens? cm
