Hello there! I just completed activities 6-8 in exercise 2 of the Phsyio Ex 8.0 book, and my professor wants me to to be able to answer some questions related to the experiments. I answered most of them, but I'm not entirely sure about these (I've bolded the questions and italicized any of the answers I've already given):

An electron microscope employs a beam of electrons to obtain an image of an object. What energy must be imparted to each electron of the beam to obtain a wavelength of 28.0 pm? Obtain the energy in electron volts (eV). (1 eV = 1.602E-19 J, mass of electron = 9.1094E-31 kg).
Finding number of photons from wavelength and energy
The retina of the eye contains two types of light-sensitive cells: rods (responsible for night vision) and cones (responsible for color vision). Rod cells are about a hundred times more sensitive to light than cone cells and are able to detect a single photon. Suppose a group of rod cells are radiated with a pulse of light having an energy equal to 1.01E-16 J. If the wavelength of t

Protein concentration assays: Warburg/Christian vs Kalb/Bernlorh
I need clarification more than anything.
Warburg and Christian method measures nucleic acids and proteins at 260/280 nm, while the Kalb and Bernlorh method measures it at 230/260. I'm confused by how it works at 230/260 -- what is being measured at these two absorbances? Also, I read in a journal article that K/B improves on that of W/C. If this is the case, why don
