Question

A typical microwave oven consists of the following major components % List

[A.] Wave guide
[B.] Magnetron
[C.] Channel
[D.] Stirrer
Choose the most appropriate answer from the options given below:

• A. A, B and D only
• B. A, B and C only
• C. B, C and D only
• D. A, C and D only

Hint:

Think of the microwave heating process: the \textbf{Magnetron} creates the waves, the \textbf{Wave guide} directs them, and the \textbf{Stirrer} (or turntable) spreads them out for even cooking.

Answer 1

The Correct Option is A

Step 1: Identify the essential components of a microwave and their roles.
B. Magnetron: The core of the microwave, this vacuum tube produces high-frequency microwaves for heating food.
A. Waveguide: A rectangular metal tube that guides microwaves from the magnetron to the oven cavity.
D. Stirrer: A rotating metal blade that distributes microwaves evenly throughout the cavity. Modern ovens often use a turntable for the same function.
C. Channel: This is not a recognized term for a primary microwave component. The key parts are the magnetron, waveguide, and a wave distribution system (stirrer or turntable).
Therefore, A, B, and D represent the correct components.
