Homework Help Overview
The problem involves calculating the kinetic energy of an electron based on its de Broglie wavelength, with specific wavelengths corresponding to atomic and nuclear sizes. The original poster has successfully calculated the kinetic energy for one case but is struggling with the second, indicating a significant discrepancy in their result.
Discussion Character
- Exploratory, Assumption checking
Approaches and Questions Raised
- The original poster attempts to calculate kinetic energy using a specific formula but questions their result for the second part of the problem. Some participants suggest checking the velocity calculated from the kinetic energy, while others raise concerns about the implications of relativistic effects at high energies.
Discussion Status
The discussion is ongoing, with participants exploring the implications of the calculations and questioning the assumptions made regarding velocity and relativistic effects. Guidance has been offered regarding the need to consider relativistic formulas if the calculated velocities approach significant fractions of the speed of light.
Contextual Notes
The original poster has indicated that they are converting kinetic energy from Joules to electronvolts, and there is a concern about the validity of their calculations in light of relativistic considerations.
