* Energy and Frequency are Directly Proportional: The energy of a wave is directly proportional to its frequency. Ciò significa che all'aumentare della frequenza, aumenta anche l'energia dell'onda.
* Planck's Relation: This relationship is described by Planck's relation:E =hν, where:
* E è l'energia dell'onda
* h is Planck's constant (a fundamental constant of nature)
* ν (nu) is the frequency of the wave
Esempi:
* Luce: Higher frequency light, like ultraviolet or X-rays, carries more energy than lower frequency light like infrared or visible light. This is why ultraviolet radiation can damage your skin, while infrared light provides warmth.
* suono: Higher frequency sound waves have a higher pitch and carry more energy. That's why a high-pitched scream can be more jarring than a low-pitched hum.
Punto chiave: Remember that frequency and wavelength are inversely proportional. So, a high frequency wave has a short wavelength, and a low frequency wave has a long wavelength.
