Would you build telescopes on the moon (& why)? If so, from the 3 wavelength regimes, namely X-ray, optical, and radio, for which one(s) would you build telescopes on the moon and why? Why do you think have we not build any telescopes on the moon (yet)?
Homework Answers
there are lots of challenges are there in making telescope on moon like
1. Extreme temperature difference between day and night on moon is very challenging
2. Moon quake ; earth exert 20 time more tidal force on moon which make it's surface unstable
3. Cost of project ; Set up of telescope and it's maintenance is very expensive in comparison to set up a telescope on earth
Hence because of these problems we didn't set up any telescope on moon till this date but among all three mentioned type of telescope Radio telescope have unprecedented advantage because on moon there is very less radio noise and this type of telescope can give us very clear images of universe but again cost comes in between due which we can't set up radio telescope on moon yet.

Suppose that in the not so distant future an astronaut on the Moon turns on a 100 W light bulb during a lunar eclipse (i.e. the Moon becomes dark as seen from Earth). You can assume that all of the emitted power is in the visble. The light is emitted uniformly in all directions. a) Calculate the number of photons per second emitted by the light bulb. b) In the dark, when your pupils are dilated, they have a diameter...

Radio wave telescope For each of these telescopes explain/discuss the following points: Give an example of what objects one would observe with this type of telescope. Discuss the location one would need to choose for this telescope. Consider the following options and explain what location is ideal for this telescope and why one would (or need to) choose one location over the...

(a) A simple telescope demo: We need to build this from scratch. We have an eyeglass lens to get started, which we could use as our eyepiece lens; we would need to buy an objective lens and a cardboard tube (from our favorite online marketplace). Assuming the eyeglass lens is a converging one and has focal length f, what type of objective lens do we need if we would like the telescope to have a magnification factor of 100? What...

1. Presume that you have not done the calculations to convert wavelength to energy yet. Only having the wavelengths of each emission line available to you, could you still answer question number 1 (without actually doing the conversion)? Explain why or why not? 2. If the 3 → 1 transition has an energy of 1.94 x 10-18 J, what do you think the energy of the 1 → 3 transition is? Explain why.

We would like to build an AM radio receiver using a series RLC
circuit working as a bandpass filter. We have decided to use a 240
μH inductor with an internal resistance of 12Ω, and a variable
capacitor whose capacitance varies between 40 to 360 pF. A radio
“tunes” into a certain frequency by adjusting its receiver circuit
so that it resonates at that frequency, and it only catches that
specific frequency.

Learning Goal: To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol A (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given...
