- Neutral hydrogens are detected with their emission lines of 21cm. What is the energy of a photon in such a line, and in which waveband would this line be observed?A planet has been discovered orbiting a K type main sequence star. A spectrum taken of this planet shows a blackbody shape to the spectrum that peaks at a wavelength of 8.67x10-5 cm. a) Find the temperature of this planet. Hint: Always make sure your units match!!!! b) Describe the prospects for life as we know it on this planet. Note that water remains in a liquid state between temperatures of 273 K and 373 K.(a) Rank the following components of the interstellar medium in order of the wavelengths at which they are observed, longest wavelength first: clouds of neutral hydrogen, coronal gas, interstellar dust, nebulae. Longest to Shortest? (b) Rank the same material in order of decreasing temperature from hottest to coolest. Hottest to Coolest?
- I am struggling to answer this question. There are two parts to this question (as shown in the picture) I have already tried the answers 6.29x10^-13 for part 1 and 65.53 for part 2 and they are both incorrect. Any help is greatly appreciated, thank you!!Infrared radiation from the center of our galaxy with a wavelength of about 2 μm (2 × 10-6 m) comes mainly from cool stars. Use this wavelength as Amax and find the temperature of the stars.How long does it take light from the sun 93 million miles away to the earth

(Select all that apply.) (1)The dust of the interstellar medium can be detected from the emission lines of elements heavier than iron. (2)The dust of the interstellar medium can be detected by the extinction of light from distant stars. (3)The dust of the interstellar medium can be detected by the scattering of blue light from distant or embedded objects. (4)The gas of the interstellar medium can be detected from the radiation of ultraviolet photons. (5)The gas of the interstellar medium can be detected from the radiation of photons of wavelength 21 cm. (6)The gas of the interstellar medium can be detected from the absorption lines present in the light from distant stars, which must be caused by a medium of a density and temperature other than that of the stars emitting the light.
