Question
Resonance cavity concept is based on ___________Select one:a. Reflection on metallic plates b. Electromagnetic waves oscillationc. Standing waves
Solution
The concept of a resonance cavity is based on standing waves. So, the correct answer is c. Standing waves.
Here's a step-by-step explanation:
-
A resonance cavity, such as those used in lasers or microwave ovens, is a space where waves are confined.
-
When waves are confined in such a space, they bounce back and forth between the walls of the cavity.
-
If the distance between the walls is just right, the waves bouncing back and forth can combine to form what's known as a standing wave.
-
Standing waves are the result of the interference of two waves moving in opposite directions. They are characterized by points that appear to be standing still, known as nodes, and points of maximum oscillation, known as antinodes.
-
The formation of standing waves is the key principle behind the operation of resonance cavities. Therefore, the concept of a resonance cavity is based on standing waves.
