Statement: An electron is accelerated through a potential difference of 150 V in a cathode ray tube. Calculate its de Broglie wavelength.
Solution:
Kinetic energy = ( e \times 150 ,\texteV = 150 ,\texteV = 150 \times 1.602\times10^-19 ,\textJ = 2.403\times10^-17 ,\textJ ).
Non-relativistic (since 150 eV << 511 keV):
[
p = \sqrt2m_e K = \sqrt2 \times 9.109\times10^-31 \times 2.403\times10^-17
]
[
= \sqrt4.377\times10^-47 \approx 6.616\times10^-24 ,\textkg·m/s
]
de Broglie wavelength:
[
\lambda = \frachp = \frac6.626\times10^-346.616\times10^-24 \approx 1.00\times10^-10 ,\textm = 1.0 ,\textÅ
]
Note: This matches the typical result: ( \lambda (\textÅ) = \sqrt150/V ) with V in volts — check: ( \lambda = \sqrt150/150 = 1 ) Å. Correct.
Paso 1: El intento honesto. Lee el problema del libro y trata de resolverlo usando tus apuntes de clase. Dedícale al menos 20-30 minutos. Apunta dónde te quedaste atascado.
Paso 2: La consulta dirigida. Abre el solucionario. No leas toda la solución. Busca específicamente la parte donde te bloqueaste. Por ejemplo: "Ah, necesitaba despejar la velocidad de la fórmula de Lorentz, pero usé la aproximación clásica".
Paso 3: El cierre. Cierra el solucionario. Resuelve el problema nuevamente desde cero, en una hoja en blanco, sin mirar. Si puedes hacerlo sin ayuda, has aprendido.
| Situation | Recommended Action | |-----------|--------------------| | Homework/Assignments | Use the solucionario only after you have attempted the problem. Cite it if your institution requires attribution. | | Exam Preparation | Treat it as a study guide; do not copy verbatim during a timed test. | | Sharing with classmates | Share conceptual explanations and method outlines, but avoid distributing scanned pages of the solution manual. | | Online forums | If you post a solution, rewrite it in your own words and give credit to the original source. |
Following these practices respects the author’s intellectual property and maximizes your own learning.
This original problem set mirrors the rigor and topics of Acosta’s Curso de Física Moderna (including problems similar to those referenced as “Acosta320”). Students are encouraged to work through each derivation and compare with results from the official textbook. For additional practice, consult university library reserves or request problem solutions directly from your instructor — never use unauthorized solution manuals.

The solutions guide typically mirrors the textbook's structure, covering essential areas such as:
Special Relativity: Time dilation, length contraction, and relativistic energy-momentum.
Quantum Theory: The photoelectric effect, Compton scattering, and the Bohr model of the atom.
Wave Mechanics: The Schrödinger equation and its applications to simple systems like the particle in a box.
Atomic and Nuclear Physics: Radioactivity, nuclear reactions, and the structure of the nucleus.
Solid State Physics: Crystal structures and the band theory of solids. Why Students Use This Resource Statement: An electron is accelerated through a potential
Verification of Methods: It allows students to confirm if their mathematical approach to a problem—such as calculating the wavelength of a De Broglie wave—is correct.
