Explanation:

* Wavelength is the distance between two successive crests or troughs of a wave.

* Frequency is the number of waves passing a point per second.

* Speed of a wave is determined by its wavelength and frequency: Speed = Wavelength x Frequency

Since the speed of light is constant, a shorter wavelength means a higher frequency. Therefore, waves with shorter wavelengths have higher frequencies and travel faster.

Example:

* Visible light: Violet light has the shortest wavelength and highest frequency, while red light has the longest wavelength and lowest frequency. Violet light travels faster than red light.

* Electromagnetic spectrum: Radio waves have very long wavelengths and low frequencies, while gamma rays have very short wavelengths and high frequencies. Gamma rays travel much faster than radio waves.

In summary:

* Shorter wavelength = Higher frequency = Faster speed

* Longer wavelength = Lower frequency = Slower speed
