Q.2: (i) Express ‘Uncertainty Principal’ briefly.

(ii) In the Davisson-Germer Experiment, what will be Bragg Scattering angle (first order) for an electron-beam when diffracted from the surface of Ni-crystalwith atomic-planes spacing D= 0.215 nm and the kinetic energy of the e-beam is approximately 75 eV.

iii. Qualitatively, discuss how the angle will change if the voltage is doubled.

*Bragg Scattering What is the Bragg Scattering angle (i.e. the angle, in degrees, between the incoming incident beam and the reflected beam) for electrons scattered from a nickel crystal if their energy is 63 eV? The spacing between Ni Bragg planes is 0.215 nm. Give your result to 3 significant figures.

What is the uncertainty of the position of the bacterium? Express your answer with the appropriate units. -------- A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 1.10 fg (where a femtogram, fg, is 10−15g) and is swimming at a velocity of v = 9.00 μm/s , with an uncertainty in the velocity of 7.00 % . E. coli bacterial cells are around 1 μm ( 10−6 m) in...

If a particle’s momentum uncertainty, what is the uncertainty in its position. Very briefly, what does this result mean? What is the Compton effect? What is measured in observations of the Compton effect? How does this differ from the expectations of classical physics? At what condition for incident radiation can the effect be observed? What important property of light does the Compton effect demonstrate? How does it give evidence of electromagnetic radiation`s particle nature?

I conducted an experiment in lab to synthesize copper(II) and iron(II) oxalate. I calculated a final mass of 7.4202g K_3[Fe(C_2O_4)_3] x 3H_2O (g). In order to find the theoretical mass of this substance, do I assume that theoretical mass is equal to the molar mass of that product formed? Then to find % yield - take the actual mass of 7.4202g/theoretical (491.326g)x100? I feel as though I am missing something here. Can someone please explain and help me solve this...
