There are a variety of artificial lights, including LEDs, incandescents and gaseous discharge. Artificial light is that which people have created in order to provide illumination for buildings.Know More
LEDs (light emitting diodes) can provide different colored light. These vary from shades like white to ones like blue, red, and green. RGB lights combine different color sources into one. These are still a newer light source than other types of artificial lights.
One of the most common light sources, incandescent bulbs provide illumination through a filament within the bulb. Halogen lamps are also a type of incandescent that use halogen gas. Fluorescents also burn gas to function.
Gaseous discharge lights work similarly to halogen lights. They utilize gas to provide illumination. High-intensity discharge lights or HIDs are also a type of gaseous discharge light that use gases such as metal halide, high pressure sodium, and mercury vapor to provide illumination.Learn more about Lighting
River pollution comes from a variety of different sources, including agricultural operations, industrial discharge, wastewater treatment plants and storm water runoff, that carry pollutants into waterways. Sources are classified as point sources if the pollution comes from a single, identifiable source and nonpoint sources if the pollution is the result of runoff over a wide area. Since rivers draw from many sources, they may contain many different pollutants.Full Answer >
High-intensity discharge, or HID, lights provide a very bright white light when compared to other types of automotive lighting, including halogen and LED lights. HID lights rely on a short electrical arc to heat up a ball of xenon gas, which leads to their bright white light and far-reaching glow.Full Answer >
Monochromatic light refers to light that is of one color. Since it only emits one color, monochromatic light has a single wavelength. Wavelengths are seen as a rainbow of colors when light is passed through a spectrum. Therefore, monochromatic light would emit just one of these colors.Full Answer >
Most commonly, light bulbs explode when manufacturers do not put enough insulation on the base of the bulb, which causes the base to melt and allows the gas stored in the light bulb to leak out. The leaking gas causes a pressure difference which results in the light bulb exploding.Full Answer >
