- Visible light and other forms of electromagnetic radiation play important roles in chemistry, since they can be used to infer the energies of electrons within atoms and molecules. Much of modern technology is based on electromagnetic radiation.
Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength .
Nov 14, 2024 · light, electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metre to radio waves measured in metres.
Jun 14, 2021 · First, we will examine the wavelike properties of light. Visible light is one type of electromagnetic radiation, which is a form of energy that exhibits wavelike behavior as it moves through space. Other types of electromagnetic radiation include gamma rays, x-rays, ultraviolet light, infrared light, microwaves, and radio waves.
Light acts as a wave and can be described by a wavelength λ and a frequency ν. One property of waves is that their speed is equal to their wavelength times their frequency. That means we have: For light, however, speed is actually a universal constant when light is travelling through a vacuum (or, to a very good approximation, air).
Apr 29, 2010 · Today, we control the inter-conversion of energy to make light from electricity, heat and chemical reactions; in our daily lives, we use chemistry and light in communication, electronics, medicine and entertainment; and photochemists are working for a cleaner, brighter future by devising new methods to convert sunlight into useful energy and to ...
Use appropriate equations to calculate related light-wave properties such as period, frequency, wavelength, and energy; Distinguish between line and continuous emission spectra; Describe the particle nature of light; Describe the Bohr model of the hydrogen atom; Use the Rydberg equation to calculate energies of light emitted or absorbed by ...
Key Points. The electromagnetic spectrum includes common regimes such as ultraviolet, visible, microwave, and radio waves. Electromagnetic waves are typically described by any of the following three physical properties: frequency (ν), wavelength (λ), or intensity (I).
