Finding the Scattering Angle of a 0.88Mev Photon & Electron

AI Thread Summary
To find the scattering angle of a 0.88 MeV photon and an electron, one must apply the principles of Compton scattering. The user has been provided with a formula related to the scattering process but lacks necessary information, specifically the wavelength (lambda). It is recommended to visit resources like HyperPhysics for a deeper understanding of Compton scattering and to derive the required formulas. The discussion emphasizes the importance of showing prior attempts at solving the problem to receive further assistance. Understanding the relationship between the photon and electron's scattering angles is crucial for solving this physics problem.

A 0.88Mev photon is scattered by a free electron initially at rest such that the scattering angle of the scattered electron is equal to the scattered photon.How to find the angle??

Hi, i tried already.My teacher only give us this formula.
lamdai =lamda o+ lamda(c)Contant* (1-cosdegree)
the problem is i don't have the other information n lamda.how to sub ?

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}...
