She bought two lenses, L 1 and L 2. out of which L 1 was bigger and L 2 was smaller. The larger lens gathers and

filestore.aqa.org.ukRefracting telescopes are relatively easy to make in the lab using a couple of lenses, a metre ruler and plasticine and this relationship can be easily investigated. The equations M = f 0 f e and distance from objective to eyepiece = fo fe can be used together to help design particular telescopes. It is fairly common to see past questions ask ...

If the particle is located below the focus, it refracts the con-verging rays (such as rays 1 and 2) as shown in1B. The corresponding reaction forces F 1 and F

www.meade.comReflecting Telescopes use a concave primary mirror to collect light and form an image. In the Newtonian type of reflector, light is reflected by a small, flat secondary mirror to the side of the main tube for observation of the image. In the refracting telescope, light is collected by a 2-element objective lens and brought to a focus at F.

Materials: • A clear medium size glass, beaker, or glass jar. • A pencil, pen, or straw. Procedure: Fill the glass about 2/3 full of water. Take the pencil and immerse it …
Reflection and Refraction
physics.fullerton.edu2 is the index of refraction of the refracting medium 1. is the angle of incidence 2. is the angle of refraction . Now let’s examine reflection and refraction at a curved surface. There are two different kinds of curved surfaces that you will be dealing with for reflection; a . concave mirror and a convex mirror.
