A 100-WW incandescent light bulb has a cylindrical tungsten filament 35.0 cm long, 0.41 mmmm in diameter, and with an emissivity of 0.28. What is the temperature of the filament? what wavelength does the spectral emittance peak?
Explain why different elements produce different spectral absorption and emission lines.  Calculate the wavelength of a photon that has an energy of  4.96 eV. (Hint: h*c {Planck's constant * the speed of light }= 1240 eV*nm;) What type of radiation/light (from the electromagnetic spectrum) is the photon from the previous question?  Why is it that radio telescopes need to be so large or organized in arrays? this is all one question with different parts. Thank you.
What is the frequency (in Hz) of an ultraviolet photon with wavelength 139 nm? Express your answer in scientific notation.
