The different wavelengths and frequencies of various forms of electromagnetic radiation are fundamentally similar in that they all travel at the same speed--about 186,000 miles per second (approximately 300,000 kilometers per second), commonly known as the speed of light (and identified with the variable c ). How does wavelength affects the frequency of the wave? Photon energy and frequency increases as the wavelength of light? The combination of all quantum numbers of all electrons in an atom is described by a wave function that complies with the Schrdinger equation. Given equal wavelengths, a wave with greater amplitude will release more energy when it falls back to sea level than a wave of lesser amplitude. The Pennsylvania State University 2020. 6.9 Why do objects absorb the way that they do?
