Compton Effect (conceptual)
Hardphysics
Compton effect demonstrates?
Select the correct option:
Solution
Incorrect! Answer:
Particle nature via photon momentum transfer
- Description: The Compton effect is the scattering of high-energy photons (X-rays/gamma rays) by electrons, resulting in an increase in the photon's wavelength.
- Mechanism: It is explained by treating the photon as a particle that 'collides' with an electron.
- Momentum Transfer: During the collision, the photon transfers some of its energy and momentum to the electron (Recoil electron).
- Proof: Since the photon loses energy, its frequency decreases (E=hf), and thus its wavelength increases (Compton Shift).
- Significance: Firmly establishes the particle nature (corpuscular theory) of light.
