Question

which wave in the diagram has the greatest frequency?
1
3
4
2

Explanation:

Step1: Recall Frequency Definition

Frequency is the number of cycles (oscillations) per unit length (or time, for time - based waves). For these waves (assuming same horizontal length), we count the number of cycles (peaks and troughs or just the number of "waves" in the given space).

Step2: Count Cycles for Each Wave

• Wave 1: Let's count the number of cycles. Visually, it has a certain number of wavy patterns.
• Wave 2: Similarly, count its cycles.
• Wave 3: It has fewer cycles as the waves are more spread out.
• Wave 4: Looking at wave 4, it has the most number of cycles (the most densely packed waves) in the given horizontal space. So, wave 4 has the greatest frequency.

Answer:

4 (the wave labeled 4)
