- Telescopes are optical devices that collect light from distant objects to form an image or a sensor. There are two types of telescopes reflecting and refracting.
- A reflecting telescope uses a curved mirror to focus all the light that falls on it. the detector is placed at its focus.
- A refracting telescope uses a lens to collect all the light and then focus it.
Step by step
Solved in 2 steps
- Which of these statements best explains why a telescope enables us to see details of a distant object such as the Moon or a planet more clearly? The image formed by the telescope is larger than the object. The image formed by the telescope extends a larger angle at the eye than the object does. The telescope can also collect radio waves that sharpen the visual imageAll these can be explained by ray optics EXCEPT: a) the resolution of telescope. b) the transmission of signals in fiber optic. c) image reversal in a mirror. d) camera lens.The focal length from a simple lens is 100 micrometers and the detector is at 500 micrometers. What is the magnification of the lens?
- Based on how it refracts light, what would you expect images formed by a concave lens to look like? The same as the objects that they are images of Reversed Smaller MagnifiedThe primary mirror on a telescope has a 43m radius of curvature and the eyepiece has a focal length of 36 mm. Determine the maginification and length of the telescope (for length, treat telescope as a refracting telescope) M = ___ L =______Distinguish between a converging lens and a diverging lens.
- A small telescope has an objective lens of focal length 144cm and an eyepiece of focal length 6.0cm. What is the magnifying power of the telescope? What is the separation between the objective and the eyepiece?What CANOT be explained by ray optics? the resolution of telescope. image reversal in a mirror. camera lens refraction. X the transmission of signals in fiber optic.
