Hi, I am Edward. I am currently pursuing the Entry-to-Practice Doctor of Pharmacy program in University of British Columbia. I am passionate in teaching and I can teach bilingually (English+Mandarin). I would love to share my studying methods and my knowledge in a simple, effective and comprehensive way with others who are interested in learning.
Explain the difference between a plot showing the probability density for an orbital and one showing the radial distribution function.
A laser pulse with wavelength 532 nm contains 3.85 $\mathrm{mJ}$ of energy. How many photons are in the laser pulse?
Determine the energy of 1 mol of photons for each kind of light. (Assume three significant figures.)$$\begin{array}{l}{\text { a. infrared radiation }(1500 \mathrm{nm})} \\ {\text { b. visible light }(500 \mathrm{nm})} \\ {\text { c. ultraviolet radiation }(150 \mathrm{nm})}\end{array}$$
Sketch the interference pattern that results from the diffraction of electrons passing through two closely spaced slits.
The resolution limit of a microscope is roughly equal to the wavelength of light used in producing the image. Electron microscopes use an electron beam (in place of photons) to produce much higher resolution images, about 0.20 $\mathrm{nm}$ in modern instruments. Assuming that the resolution of an electron microscope is equal to the de Broglie wavelength of the electrons used, to what speed must the electrons be accelerated to obtain a resolution of 0.20 $\mathrm{nm}$ ?
Calculate the de Broglie wavelength of a $143-$ baseball traveling at 95 mph. Why is the wave nature of matter not important for a baseball?
