Question

which wave has the highest frequency? b a

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, constant for waves in the same medium). So \( f=\frac{v}{\lambda} \), which means frequency is inversely proportional to wavelength.

Step2: Compare the wavelengths of wave A and wave B

Looking at the diagram (assuming standard wave - representation where more oscillations in a given space mean higher frequency), wave A has a shorter wavelength than wave B.

Since \( f=\frac{v}{\lambda} \) and \( v \) is constant (same medium), a shorter wavelength \( \lambda \) implies a higher frequency \( f \).

Answer:

A
