Refracting Telescopes

Refracting Telescopes. Refracting Telescopes. This kind of telescope also has two convex lenses, the objective lens and the eyepiece. Refracting Telescopes. In refracting telescopes, the objective lens is much bigger, so the focal length is farther, so the telescope is longer too.

Lenses. Physics 202 Professor Lee Carkner Lecture 23. Refraction. Mirrors can be used to magnify an object or to gather light Lenses can be used for the same purposes Lenses gather light and magnify objects through refraction instead of reflection

Index of Refraction

Index of Refraction. Index of refraction of a material equals the speed of light in a vacuum divided by the speed of light in the material. Because of atmospheric refraction, we have lingering, elliptical sunsets. Sun. Earth. Sun. Mirage. Cool air. Warm air. Surface of water?.

Lenses

Lenses. As light enters into a new medium it may bend due to refraction. So on a flat piece of glass all light rays remain parallel. Snells Law states that the ratio of the sin of the angle of incidence to the sin of the angle of refraction is a constant for each material. Lenses.

LIGHT

LIGHT. TLW explore what you see when you mix colors of light. TLW describe visible light as a part of the electromagnetic spectrum. TLW compare reflection and refraction of light. TLW explain why we see the colors of objects. What is Light?. A form of energy that travels in waves

6.2 Extending Human Vision

6.2 Extending Human Vision. Microscopes A compound light microscope uses two convex lenses to magnify small, close objects. Magnify means to make the image look larger than the real size. To focus the image, the object is moved closer to or farther away from the object lens.
