Can a Body Exceed 3/4 Speed of Light in Water?

Click For Summary
SUMMARY

A body can exceed 3/4 the speed of light in water, particularly weakly interacting particles such as neutrinos, which are minimally affected by their environment. This phenomenon is associated with Cherenkov radiation, which occurs when a particle travels faster than the speed of light in a medium, analogous to a sonic boom in air. Cherenkov radiation is emitted at a specific angle relative to the particle's trajectory, marking its presence and speed. Understanding these principles is crucial for fields involving particle physics and high-energy phenomena.

PREREQUISITES
  • Understanding of Cherenkov radiation
  • Basic knowledge of particle physics
  • Familiarity with the concept of speed of light in different media
  • Knowledge of weakly interacting particles, specifically neutrinos
NEXT STEPS
  • Research the properties and behavior of Cherenkov radiation
  • Study the physics of neutrinos and their interactions
  • Explore the implications of exceeding light speed in various mediums
  • Investigate applications of Cherenkov radiation in experimental physics
USEFUL FOR

Physicists, researchers in particle physics, and students studying advanced concepts in relativistic physics will benefit from this discussion.

Can a body exceed 3/4 the speed of light in water.
 
Science news on Phys.org
Weakly interacting particles, with no charge, like the neutrinos, will (almost) not be affected by water or any other environment.
Such particles will maintain their existing velocity, close to the speed of light in the neutrinos case.
 
then will a phenomenon like sonic boom would occur?
 
Cherenkov effect is analogous to sonic boom for sound.
 
Yes, there would be Cherenkov radiation radiating at a certain angle to the trajectory of the particle.
