Four sets of tees, large Penncross bentgrass greens protected by strategic bunkering and mounds, generous and gently rolling fairways, many elevation changes, lots of water and the ever-present wind combine to make Bretwood a favorite of recreational and competitive golfers alike.
The longer wavelengths (red) and the shorter wavelengths (blue) are separated. Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400â700 nanometres, or 4.00 Ã 10â7 to 7.00 Ã 10â7 m, between the infrared and the ultraviolet. This wavelength means a frequency range of roughly 430â750 terahertz. The main source of light on Earth is ...
Light is a electromagnetic wave. This wave has a wavelength that can be measured in meters. Of course light waves are very small. Shown below is a chart showing the relationship between the length of the light wave in nanometers as a function of the color of light we humans are able to observe.
