AS101 Lecture Notes - Adaptive Optics, Electromagnetic Spectrum, Light Pollution
Document Summary
Telescope notes i light changes direction when it interacts with matter. Refracted: the bending of light when it is passing through a new medium. Ex: the refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. Use the same angle; no bending of light. Special property: parabolic mirrors take their incoming rays of light and converge it into one ray refractive use primary lenses to bend the light and bring it to focus. But they are not the best because . The have chromatic abbreviation: different wavelengths are focused at different sections meaning the image is reliable as the light isn"t the same. Eyepiece is used to magnify inverted image reflective. Primary mirror reflects the light back to a focus instead of refracting it.
