Q1: The results of a photoelectric experiment comparing two different metals (A and B) are shown below. A B Frequency of light In the experiment, the KE of the photoelectrons is plotted vs. the frequency of the light used for each of the metals. Which metal has the greater p? Group of answer choices: B/cannot be determined/A Photoelectron KE

O Macmillan Learning Consider the four scenarios involving visible light. In scenario A, visible light has a wavelength of 713.0 nm. Determine its frequency, energy per photon, and color. energy per photon: In scenario B, visible light has a frequency of 5.697 x 10¹4 s¹. Determine its wavelength, energy per photon, and color. energy per photon: J J frequency: The visible light in scenario A is wavelength: The visible light in scenario B is S-1 nm

Convert between number of photons and energy given a particular wavelength. Low level light therapy (LLLT) using RED light was observed to promote wound healing. The daily dose provided was 24 J/cm. Given the wavelength of 635 nm, how many photons were required to deliver the dose to a 1 cm? area?
