Fresh out of university you've been hired to do some photoelectron spectroscopy. You have a lamp that outputs an unknown wavelength of light. When the light is incident on a metal with a work function of 6.31 eV, you observe a stopping voltage equal to 4.21 V. What is the wavelength of the light? (unit in nm).
A 117.0W lightbulb emits about 7.45W of visible light. (The other 109.55W are emitted as infrared radiation or lost as heat to the surroundings.) The average wavelength of the visible light is about 570.0nm, so make the simplifying assumption that all the visible light has this wavelength. What is the frequency of the emitted visible light?
How many visible-light photons does the bulb emit per second?
