- If a sunspot has a temperature of 4,430 K and the sunspot can be considered a blackbody, what is the wavelength (in nm) of maximum intensity of the sunspot's radiation?The planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…If Neptune's clouds have a temperature of 60 K, at what wavelength will they radiate the most energy?
- Using this equation Wein's Law: What is the wavelength of maximum intensity and the total energy emitted by a celestial object at absolute zero?Earth tugs the Sun around as it orbits, but it affects the radial velocity of the sun by only 0.09m/s. How large a shift in wavelength does this cause in the Sun's spectrum at 575 nm?b) What is Hopkinson’s law?Explain with the help of equation.
- A photon has a wavelength of 581 nm. What is the energy of the photon (in units of 10-19 Joules)? Your Answer: AnswerExplain why the presence of spectral lines of a given element in the solar spectrum tells you that element is present in the sun, but the absence of the lines would not necessarily mean the element is absent from the sun.
