Discussion Overview
The discussion revolves around the applicability of Planck's constant equation and related equations in calculating the speed of particles, specifically electrons. Participants explore whether the equations c=hv and c=lambda(v) can be used interchangeably with particle speed (u) in various contexts, including the relationships between frequency, wavelength, and speed.
Discussion Character
- Exploratory
- Debate/contested
- Mathematical reasoning
Main Points Raised
- Some participants question whether the equation c=hv can be modified to u=hv for calculating the speed of a particle given its frequency.
- Others point out that the equation c=hv is actually E=hv, indicating a potential misunderstanding of the equations involved.
- One participant clarifies that the equation c=lambda(v) relates to the speed of light and asks if it can be used for particle speed instead.
- Another participant asserts that the equation c=lambda(frequency) is specific to electromagnetic waves in a vacuum and suggests that other equations, such as the de Broglie relations, should be used for particles.
Areas of Agreement / Disagreement
Participants express differing views on the applicability of the equations for calculating particle speed, indicating that there is no consensus on whether these equations can be used interchangeably with particle speed.
Contextual Notes
There are unresolved assumptions regarding the conditions under which the equations apply, particularly the distinction between electromagnetic waves and particles, as well as the specific contexts in which each equation is valid.
