Amplitude is a crucial character of a wave that helps determine the nature of the wave's energy. So the longer the wavelengths and lower the frequency results in lower energy. How does the temperature affect the intensity of the wavelength of light emitted How does it affect the wavelength of the maximum intensity light emitted? So when the wavelength is increased, the energy is The energy of a photon is given by the equation E = hf, where E is energy, h is Plancks constant, and f is frequency. The higher the frequency, the more energy, and the higher the amplitude, the more energy. The energy of a photon depends on radiation frequency; there are photons of all energies from high-energy gamma- and X-rays, through visible light, to low-energy infrared and radio waves. As the wavelength of light increases the frequency decreases. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Where does the term bum a cigarette come from? For an adult human being moving at the same speed, our wavelength is a minuscule 10 32 meters, or just a few hundred times larger than the Planck scale: the length scale at which physics ceases to make sense.

This relationship holds for any traveling waves - electromagnetic (EM) or sound, for example. As a wavelength increases in size, its frequency and energy (E) decrease. frequency, the energy will decrease as well in this case. Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. How does the wavelength change when you increase or decrease the frequency does it vary as expected explain? . The shorter the wavelength, the more energetic is the photon, the longer the wavelength, the less energetic is the photon. Science, 28.10.2019 17:29, JUMAIRAHtheOTAKU. There is Radio waves, Microwaves, infrared, visible light, ultra violet, X-ray and Gamma ray. 6.1 Atmospheric Radiation: Why does it matter? 8.
