Question

which wave has the greater wavelength? they both have the same wavelength there is no wavelength shown a1 a2

Explanation:

Step1: Understand wavelength definition

Wavelength is the distance between two consecutive crests (or troughs) of a wave.

Step2: Analyze the given waves

Looking at the graph, for both waves (the solid - line wave \(A_1\) and the dashed - line wave \(A_2\)), the distance between consecutive crests (or troughs) is the same.

Answer:

They both have the same wavelength
