Which research technique did C.F. Powell reintroduce?
Bubble chamber method
Photographic method
Scanning tunneling microscopy
Electron microscopy
Answer
The photographic method, reintroduced by C.F. Powell, is a research technique used to detect and study charged particles such as protons, electrons, and mesons. It involves the use of photographic emulsions, where the particles leave tracks as they pass through the emulsion. These tracks can then be examined under a microscope or scanned and analyzed electronically to determine the properties of the particles, such as their energy and momentum.
