How Do You Calculate Wavelength and Recoil Velocity in Nuclear Physics Problems?

AI Thread Summary
To calculate the wavelength of a gamma ray when 50% of its energy becomes kinetic energy, one must apply the energy-wavelength relationship from quantum mechanics. For the recoil velocity of a nucleus losing mass during gamma decay, the conservation of momentum and the relationship between mass loss and recoil can be utilized. The discussion highlights a lack of understanding of the relevant equations, indicating a need for foundational knowledge in nuclear physics. Participants emphasize the importance of showing attempts at solutions for better guidance. Overall, the thread underscores the necessity of grasping fundamental concepts in nuclear physics to solve these problems effectively.

Homework Statement


hey, 2 questions thanks:
1.A gamma ray is converted to an electron and a positron. If 50% of the gamma ray energy becomes kinetic energy, what is the wavelength of the gamma ray?

2.A nucleus of a radioactive element (mass 10^-25) loses 10^-26g during gamma decay. if the gamma ray has a wavelength of 10^-14m, what is the recoil velocity of the nucleus?


Homework Equations


no idea, we haven't learned about wavelength at all.. however these two questions were in a big revision booklet so id rather be safe than sorry.


The Attempt at a Solution



thanks.

You looks like you are just throwing question insincerely to board us to answer. Try to write more carful next time. If you show your attempt, I will tell you the answer. And If you haven't learn it, don't worry. You will be perfectly safe.
 
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'

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...
