below. 16.) Calculate the wavelength of the He-Ne laser, as shown in the figure Collision Helium p Neon 1.96 eV E3 E2 20.61 eV 20.66 eV 18.70 ev Eo 0 17.) Suppose a star with radius 8.50 x 108 m has a peak wavelength of 685 nm in the spectrum of its emitted radiation. (A) What is the energy of a photon with this wavelength? (B) What is the surface temperature of the star? (C) At what rate is energy...
What is the peak wavelength of light coming from a star with a temperature of 7,750 K? (Submit your answer in nanometers. Remember 1nm = 10-9 m)
Number three please The temperature of a student's skin is 33.0 degree C. At what wavelength does the radiation emitted from the skin reach its peak? The radius of our Sun is 6.96 times 10^8 m, and its total power output is 3.85 times 10^26 W. (a) Assuming the Sun's surface emits as a black body, calculate its surface temperature. (b) Using the result of part (a), find lambda_max for the Sun. Calculate the energy in electron volts of a...
Question 1: at what peak wavelength does your body radiate the most given that your temperateure is approximately that of earth, which is 300k? What kind of light is this? Question 2: where would you expect the peak wavvelength of jupiter's spectrum to be? why?

PLS HELP ASAP ONE ATTEMPT What is the wavelength of light (in nm) emitted when an electron in a hydrogen atom undergoes a transition from the n 4 energy state to the n 2 energy state? Express your answer to the nearest nm Answer Check
17. It takes 254 kJ/mol to eject electrons from a certain metal surface. What is the longest wavelength of light (nm) that can be used to eject electrons from the surface of this metal via the photoelectric effect 18. Why does this question ask you about the 'longest wavelength of radiation, rather than the 'shortest'? 19. When radiation of wavelength 2.45 x 10'm falls on a metal surface, the maximum kinetic energy of the emitted electrons is found to be...
