1. What is the energy (in joules) of an ultraviolet photon with wavelength 150 nmnm ?
Express your answer in joules to two significant figures.
2. What is its frequency?
Express your answer in hertz to two significant figures.
I included an image of what I had entered in as my answer but it was incorrect. I realized I put in 3 significant figures but I may not have changed it correctly.
I'm also not sure that I obtained the correct answer either way. I worked out frequency to be .002 but that is also incorrect.
I don't know how to work with converting units too well so that may be my biggest issue here, would you please help explain what I'm doing wrong or the correct way to do it?
