8.7 Summary Notes - Detectunf Subatomic Particles

Question 1

What are bubble chambers?

Answer 1

Detection chambers used to detect and analyze the nature of moving particles. It is filled with a superheated liquid on the verge of boiling. When a charged particle passes through, its kinetic energy will. Cause the liquid to boil along its path, leaving a thin visible trail of bubbles.

Question 2

Characteristic of tracks

Answer 2

Positive and negative particles curve in opposite directions

Lighter particles tend to curve more

All conservation laws must be obeyed

Neutral particles don’t leave tracks
