Does high frequency mean longer wavelength

A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.

Wave frequency is related to wave energy. Since all that waves really are is traveling energy, the more energy in a wave, the higher its frequency. The lower the frequency is, the less energy in the wave . Following the above examples, gamma rays have very high energy and radio waves are low-energy.

Waves with higher frequencies have shorter wavelengths and, therefore, have more oscillations per unit time than lower-frequency waves . Higher-frequency waves also contain more energy than lower-frequency waves. This energy is delivered as elementary particles called photons.
