You have a telescope that consists of two converging lenses which are placed a distance apart which is approximately equal to the sum of their focal lengths. Focal length 1 is appriximatly 5.5cm and focal length 2 is approximatly 25cm.  The lens closest to the onject should have a resonably long focal length and the eyepiece lens should have a relatively short focal length to get good magnification.   a. draw a scale ray diagram for a telescope using one long and one short focal length lens. b. Estimate how much larger your distance object appears through your telescope and then calculate the angular magnification.

Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.
