Question

select one
what is the wavelength of the wave above?
40 cm
10 cm
20 cm

Explanation:

Step1: Understand the concept of wavelength

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

Step2: Identify crests in the graph

In the given graph, the first crest is at \(x = 10\) cm and the next crest is at \(x = 50\) cm.

Step3: Calculate the wavelength

The formula for wavelength \(\lambda\) is \(\lambda=x_{2}-x_{1}\). Substituting \(x_{1} = 10\) cm and \(x_{2}=50\) cm, we get \(\lambda = 50 - 10=40\) cm.

Answer:

\(40\) cm
