Chapter 6, Problem 1E
What are the three basic components of a modern astronomical instrument? Describe each in one to two sentences.
Expert Solution & Answer
To determine
The three basic components of a modern astronomical instrument.
Answer to Problem 1E
The three basic components of a modern astronomical instrument are the telescopes, the wavelength sorting device and the detectors.
Explanation of Solution
The three basic components of a modern astronomical instrument are the wavelength sorting device, the telescopes and the detectors.
- The telescopes:
- The wavelength sorting device:
- The detectors:
It is an optical device used for observing distant objects so that they appear near. It consists of an arrangement of lenses or a curved mirror. It is used to collect faint light from astronomical objects and focus all the light into a magnified image.
After the telescope collects light, an instrument is used which can sort light according to its wavelength.
Detectors are electronic devices which permanently record data so that it can be analyzed later. Visible light detectors can be the human eye which can observe at observatories located far away on Earth using computers, other detectors are photographic films.
Conclusion:
Thus, the three basic components of a modern astronomical instrument are the telescopes, the wavelength sorting device and the detectors.

In the pivot assignment, we observed waves moving on a string stretched by hanging
weights. We noticed that certain frequencies produced standing waves. One such
situation is shown below:

- Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor.
