Road surface marking is any kind of device or material that is used on a road surface in order to convey official information; they are commonly placed with road marking machines (or road marking equipment, pavement marking equipment).They can also be applied
By connecting a light dependant resistor to the Wheatstone bridge circuit above, we can monitor and measure any changes in the light levels as shown. Wheatstone Bridge Light Detector The LDR photocell is connected into the Wheatstone Bridge circuit as shown to produce a light sensitive switch that activates when the light level being sensed goes above or below the pre-set value determined by V
History Clocks with weights, gears and regulators inspired devices, most often with no dial, that struck the important moments of community life. In 1291, Prince Asulid of Yemen made a remarkable astrolabe. World history The Mongols invaded Central Asia and
The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids

[10] The red, blue, and green lines represent contours of constant market-weighted aggregate ownership costs of light for incandescent, fluorescent, and HID lighting in 2001. Filled tan circles represent past and present SSL (packaged but not
Artificial lights raise night sky luminance, creating the most visible effect of light pollution—artificial skyglow. Despite the increasing interest among scientists in fields such as ecology, astronomy, health care, and land-use planning, light pollution lacks a current quantification of its magnitude on a global scale. To overcome this, we present the world atlas of artificial sky
Blocking diodes are used to keep batteries from releasing in reverse through the solar panel boards during the evening. Current streams from high to low voltage, so on a bright day, the voltage of a panel board will be higher than the voltage of a profound cycle battery
