The correct relationship between frequency and wavelength of a wave is: Higher frequency, shorter wavelength.
This relationship can be summarized by the equation:
\[ v = f \lambda \]
where:
- \( v \) is the wave speed,
- \( f \) is the frequency,
- \( \lambda \) is the wavelength.
In this equation, if the speed of the wave (v) remains constant, an increase in frequency (f) will result in a decrease in wavelength (λ), and vice versa.
