🔍 Key Concepts

• Meaning of the term cathode in basic electronics or radar displays • What a cathode ray tube (CRT) actually uses to form an image • Difference between an electron beam and signal processing terms like noise or gain

💭 Think About

• Which choice best matches what is physically produced inside a traditional radar or older TV display tube? • Do any of the choices describe a physical stream of charged particles starting from a cathode? • Are any of the options talking about mathematical or signal-processing concepts rather than a physical ray?

✅ Before You Answer

• Make sure you know that a cathode is a negatively charged electrode that emits electrons • Confirm which option refers to a beam of electrons rather than a property like gain or noise • Eliminate any options that describe mathematical or statistical ideas instead of a physical phenomenon
