Light, radio, ultraviolet, and gamma rays are all forms of electromagnetic radiation. The extent of the shift is directly proportional to the observer's radial velocity relative to the source. Motion toward the source causes a blueshift. Any net motion away from the source causes a redshifta shift to lower frequenciesin the received beam. This motion-induced change in the observed frequency of a wave is called the Doppler effect. Our perception of the wavelength of a beam of light can be altered by our velocity relative to the source. Stefan's law states that the total amount of energy radiated is proportional to the fourth power of the temperature. Wien's law tells us that the wavelength at which the object radiates most energy is inversely proportional to its temperature. The intensity of radiation of different frequencies emitted by a hot object has a characteristic distribution, called a blackbody curve, that depends only on the temperature of the object. The temperature of an object is a measure of the speed with which its constituent particles move. Only radio waves, some infrared wavelengths, and visible light can penetrate the atmosphere and reach the ground from space. The opacity of Earth's atmospherethe extent to which it absorbs radiationvaries greatly with wavelength. The entire electromagnetic spectrum consists of (in order of increasing frequency) radio waves, infrared radiation, visible light, ultraviolet radiation, X rays, and gamma rays. The color of visible light is simply a measure of its wavelengthred light has a longer wavelength than blue light. Different frequencies of light within the beam are refracted by different amounts, so the beam is split up into its component colorsthe visible spectrum. Both electric and magnetic fields are involved, so the phenomenon is known as electromagnetism.Ī beam of white light is bent, or refracted, as it passes through a prism. The information travels in the form of a wave at the speed of light. When a charged particle moves, information about that motion is transmitted throughout the universe by the particle's changing electric field. Like gravitational fields, electric fields decrease as the square of the distance from their source.

Any electrically charged object is surrounded by an electric field that determines the force it exerts on other charged objects. Interference is the ability of two waves to reinforce or partially cancel each other.Įlectrons and protons are elementary particles that carry equal and opposite electrical charges. Diffraction is the tendency of a wave to spread out after passing through an opening or to bend around a corner. The wave frequency is simply 1 divided by the wave periodit counts the number of wave crests that pass a given point in one second. A wave is characterized by the wave period, the length of time taken for one complete cycle the wavelength, the distance between successive wave crests and the wave amplitude, which measures the size of the disturbance associated with the wave. Visible light is a particular type of electromagnetic radiation and travels through space in the form of a wave.
