Calculating Emission Wavelength for Excited Atoms at 3.031x10^-19 J Energy Level

AI Thread Summary
To calculate the emission wavelength for excited atoms at an energy level of 3.031×10^-19 J, the relevant equation is λ = hc/E. Here, h represents Planck's constant (approximately 6.626 x 10^-34 J·s) and c is the speed of light (approximately 3.00 x 10^8 m/s). Substituting these values into the equation allows for the determination of the wavelength. The discussion emphasizes the importance of understanding these constants to solve the problem effectively. Accurate calculations will yield the desired emission wavelength for the excited atoms.

What is ##h##? what is ##c##?

If you don not know, go to "photon energy" wiki page.
 
Thread 'Collision of a bullet on a rod-string system: query'

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...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
