Light, X-Rays, infrared and microwaves
- Light, X-Rays, infrared and microwaves are among the types of electromagnetic waves.
Examples of light include radio and infrared waves, visible light, ultraviolet radiation, and X-rays. Interestingly, not all light phenomena can be explained by Maxwell’s theory. Experiments performed early in the twentieth century showed that light has corpuscular, or particle-like, properties.

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...
Light travels very fast - at the speed of light in fact!Light travels as waves.Light travels in straight lines.Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference . Like all electromagnetic waves, light can travel through a vacuum.
Knowing about the wave nature of light helps us interpret the different types of light that astronomical objects emit. In turn, this allows us to employ those waves to learn more about the processes that affect the formation and evolution of stars, galaxies, and the Universe itself.
Nov 14, 2024 · This article focuses on the physical characteristics of light and the theoretical models that describe the nature of light. Its major themes include introductions to the fundamentals of geometrical optics, classical electromagnetic waves and the interference effects associated with those waves, and the foundational ideas of the quantum theory ...
Explain the basic behavior of waves, including traveling waves and standing waves. Describe the wave nature of light. Use appropriate equations to calculate related light-wave properties such as period, frequency, wavelength, and energy. Distinguish between line and continuous emission spectra.
Nov 14, 2024 · From ripples on a pond to deep ocean swells, sound waves, and light, all waves share some basic characteristics. Broadly speaking, a wave is a disturbance that propagates through space. Most waves move through a supporting medium, with the disturbance being a physical displacement of the medium.
