Plotting energy as a function of wavelength

AI Thread Summary
The discussion focuses on plotting the energy of an electron ejected from a material as a function of wavelength, given a work function of 2 eV. The equation used is E = h(c/λ) - 2, leading to a graph that approaches infinity as the wavelength approaches zero and crosses the x-axis at 6000 angstroms. Participants confirm that this graph shape is expected, as very small wavelengths correspond to high-energy gamma rays, resulting in diverging energy values. The analysis aligns with the principles of photoelectric effect, validating the approach taken. The conclusions drawn about the graph's behavior are accurate and reflect the underlying physics.

Homework Statement



Given work function W=2eV
Plot energy of an electron knocked off with respect to wavelength

Homework Equations


E=hv-W

The Attempt at a Solution


E=h (c/(lambda))-2
I plotted this and I get a function that goes to infinity with zero wavelength and crosses the x-axis at 6000 angstroms. I was just wondering if this shape of graph makes sense of if I'm just way off[/B]

Very small wavelengths correspond to gamma rays, and the energy diverges if you go close to zero.
Yes, that is the expected shape for the maximal energy of electrons.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
