Experiment geometrical optics

Experiment - Geometrical Optics. This lab consists of many short optics experiments. You will be introduced to ray optics and image formation in this experiment. We will use the optical rail, lenses and the.

Geometric optics is the technology that underlies most of the optical devices important to various aspects of our lives.

These range from simple things like eyeglasses to complex instruments, such as the Hubble Space Telescope.

Significant changes have been made since then, and the manual used during the current academic year is in NOT available yet on the WEB.

Hardcopies can be purchased at the bookstore. Geometric optics treats light as rays that travel in straight lines and refract at the boundaries between different optical media. This short intro will show off the main steps to the geometric optics lab.

The locations of the source, object, umbra and pen-umbra can be marked on the sheet of . Compare with Newtonian telescope. The index of refraction is basic to all optical lenses and fiber optics. Please do the other experiments in order. The method of geometrical optics will not solve all problems that involve light. Many situations can be treated by either metho but where there . The purpose of this experiment is to verify the thin lens equation and to construct simple optical systems using various combinations of lenses.

Lenses produce different types of images, depending on the position of the object relative to the lens and its focal . Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen. GEOMETRICAL OPTICS - OPTICAL INSTRUMENTS. Most optical elements (mirrors, lenses) can be . Physics: Home-made lenses - Science experiment.

Lenses of wax are an inexpensive way how students can learn the basics of geometrical optics. Making lenses is suitable for school project days, science days, fairs. The quality of the lens is dependent on the accuracy of manufacture. Relatedness to medicine and purpose of the experiment. Basic knowledge in geometric optics is required in the usage of several medicinal devices for dia- gnostic analysis, e. Not least, it is vital for the compre- hension of the working . Complete electromagnetic descriptions of light are, however, often difficult to apply in practice.

Practical optics is usually done using simplified models. The most common of these, geometric optics , treats light as a . It is proposed in this paper that many geometrical optical illusions, as well as illusory patterns due to motion signals in line drawings, are due to the statistics of visual. In experiments with this illusion it has also been found that the effect decreases with an increasingly acute angle between the main line and the obliques, .

In this laboratory, we will perform several experiments on “ geometric ” optics. A pictorial diagram of the various components to be used is shown in Figure 5.
