What are the equations and solutions for the De Broglie Wavelength Problem?

AI Thread Summary
The discussion focuses on calculating the wavelength of a 6.0 eV photon and the de Broglie wavelength of a 6.0 eV electron. The relevant equations include λ = h/p for the de Broglie wavelength and f = E/h for frequency, along with the relationship c = λf. Participants suggest looking up solutions in textbooks or online resources for further clarification. The conversation emphasizes the importance of understanding the velocity of particles in these calculations. Overall, the thread provides insights into solving the De Broglie wavelength problem using established physics equations.

Physics news on Phys.org
\lambda=\frac{h}{mv}
 
what about the velocity?

nevermind use this formula

f = \frac{E}{h}

and c = \lambda f

by th way this is probably in your textbook or in your notes...

you can also look this up on wikipedia, for example
 
I've already solved part a. The De Broglie wavelength is given by the equation lambda=h/p.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
