Question

which wave has the largest wavelength?

Explanation:

Step1: Understand wavelength definition

Wavelength is the distance between two consecutive identical points (e.g., crest - to - crest or trough - to - trough) on a wave.

Step2: Compare wave patterns

Looking at the waves: Wave B has fewer oscillations (cycles) in the given space compared to A and C. Fewer oscillations mean larger distance between consecutive identical points (wavelength).

Answer:

B
