What is the focal length of a convex lens of focal length30cmin contact with a concave lens of focal length20cm. Is the system a converging or a diverging lens ? Ignore thickness of the lenses. View Solution A lens behaves as a diverging lens in air and converging lens in water.The ref...
A convex lens (also known as a converging lens) and a concave lens (also called a diverging lens) focus light at different points. This information will change your focal length calculation. An online focal length calculator can help you make these calculations. You can also determine focal ...
A convex lensconverges the light rays of a parallel beam to a point after refraction through it. Hence a convex lens is also called a converging lens. A concave lens diverges the light rays of a parallel beam after refraction through it, Hence a concave lens is also called a diverging len...
An object is placed 13.3 cm away from a convex mirror with a focal length of magnitude 7.00 cm. (a) Is the sign of the focal length negative or positive? (b) Find the image distance q. A concave, spherical mirror and a thin, converging lens are both measured in air (n =...
Answer to: Calculate the image, position and height. A 2.0 cm-tall object is 40 cm in front of a converging lens that has a 20 cm focal length. By...
Whatever the mix of surfaces, if the lens is thicker at its center than its edges it is called a converging lens (having positive focal length). If it is thinner
