Question

You want to study a biological specimen by means of a wavelength of 20.0 nm and have a choice of using electromagnetic waves or an electron microscope. A. Calculate the ratio of the energy of a 20.0 nm-wavelength photon to the kinetic energy of a 20.0 nm-wavelength electron. B. In view of your answer to part A, which would be less damaging to the specimen you are studying, photons or electrons?

Step 1

First, we need to find the energy of a 20.0 nm-wavelength photon. We can use the formula: $E_{photon} = \dfrac{hc}{\lambda}$ where $E_{photon}$ is the energy of the photon, $h$ is Planck's constant ($6.63 \times 10^{-34} \, Js$), $c$ is the speed of light ($3.00 Show more…
