Question

select one which wave has the higher frequency? they have the same frequency wave a has the higher frequency wave b has the higher frequency

Explanation:

Step1: Recall the relationship between frequency and wavelength

Frequency \( f \) and wavelength \( \lambda \) are related by the formula \( v = f\lambda \) (where \( v \) is the wave - speed). For waves in the same medium (same \( v \)), \( f=\frac{v}{\lambda} \). A shorter wavelength means a higher frequency.

Step2: Compare the wavelengths of Wave A and Wave B

Looking at the displacement - graph, Wave B has a shorter wavelength (the distance between two consecutive crests or troughs is smaller for Wave B compared to Wave A).

Answer:

Wave B has the higher frequency
