🔍 Key Concepts

• Relationship between heat and electron emission from metals • Difference between light-caused emission and heat-caused emission • Basic operation of vacuum tubes / electron tubes

💭 Think About

• Which option name sounds like it is directly related to heating a material until electrons are emitted? • Which option would more likely describe electrons knocked out by incoming particles or photons, rather than just by heating? • Think about old vacuum tubes in radios and amplifiers: what kind of emission took place from their heated cathodes?

✅ Before You Answer

• Identify which term is associated with a hot filament or heated metal cathode. • Eliminate any choice that clearly refers to light (photons) as the cause of electron emission. • Eliminate any term that does not commonly appear in discussions of vacuum tubes or electron guns.
