alleryUltraviolet light causing emission was studied in detail by:
AHallwachs and Lenard
BNewton and Hooke
CBohr and Sommerfeld
DCurie and Becquerel
Answer & Solution
Correct answer: A. Hallwachs and Lenard
1. Hertz noticed the effect but did not pursue it.
2. Two later experimenters studied it through the eighteen nineties.
3. They were Hallwachs and Lenard.
