Why do electrical lights not have the ability to fill dark corners of a room during daylight hours as they do so efficiently during nightlight hours?
It's called "Contrast". At night the Electric light is much brighter than the surrounding "Ambient" light so it "appears" to brighten up the corners of a dark room in "Contrast" to the ambient light. But, during the day the "Ambient" light is so much brighter than the Electric light that it does not "appear" to have the same effect. Part of this is due to your eyes. Since your eyes adjust to different levels of light, to help you see better under varying light conditions. In the dark of night your Iris is wide open to allow more light in, thus the Electric light "looks" bright. But, during the day your Iris is closed down to not let so much light in (if it stayed open you would not be able to see well due to so much light getting into your eye that it would "white out" everything) so the Electric light actually "appears" to be dark. A good example of "Contrast" is Sun Spots. Sun Spots "appear" to be "dark spots" on the surface of the sun. In actuallity they are so bright that if you were to look at them without some sort of eye protection (dark glasses) the brightness could blind you. The reason they "appear" dark is that the surrounding areas of the surface of the sun are thousands of degrees hotter than the sun spot areas. TommyTrouble
What else can I help you with?
How did the ability to work with iron affect food production and the types of jobs that villagers performed inb west Africa?
with iron tools, farmers could clear land and grow crops more efficiently. it also helped with weaving, metalworking, and pottery making.
What is capacitance?
Theoretically, Capacitance is defined as the ability of a component or circuit to collect and store energy in the form of an electrical charge. Mathematically, it is defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential.
What is the protusion on the front of a ship at the water line?
The protrusion on the front of a ship at the waterline is called the "bow." It is designed to cut through the water efficiently, reducing resistance and improving the vessel's hydrodynamics. The shape and design of the bow can significantly affect a ship's performance, stability, and ability to navigate through waves.
What is Edwards vampire ability?
His ability only unique to HIM is the ability to read minds. except Bella's of course since she has her own ability even as a human.
Was elected chairman of the meeting?
The elected chairman of the meeting was chosen to lead the proceedings and ensure that discussions were conducted efficiently and fairly. This individual was likely selected based on their experience, ability to facilitate dialogue, and knowledge of the agenda. The chairman's role includes guiding the conversation, managing time, and ensuring that all voices are heard. Their leadership is crucial for achieving the meeting's objectives.
What is the ability to transmit heat or ectrisity called?
The ability to transmit heat is called thermal conductivity, while the ability to transmit electricity is called electrical conductivity. These properties determine how efficiently heat or electricity can flow through a material.
How can electrical conductivity be measured accurately and efficiently?
Electrical conductivity can be accurately and efficiently measured using a device called a conductivity meter. This device measures the ability of a substance to conduct electricity by passing a small electrical current through it and measuring the resulting conductivity. The conductivity meter provides a numerical value that indicates the conductivity of the substance being tested.
What is the greatest conductor of energy?
The greatest conductor of energy is silver, due to its high electrical and thermal conductivity properties. Silver is commonly used in electrical applications, such as electrical wiring and circuit boards, because of its ability to efficiently transfer energy.
Why does the cold drain batteries?
The cold drains batteries because it slows down the chemical reactions inside the battery, reducing its ability to generate and store electrical energy efficiently.
Is copper conductor?
Yes, it is highly conductive.
Is coper a conductor?
Yes, copper is a highly effective conductor of electricity due to its low electrical resistance. It is used in various electrical applications, including wiring and circuitry, because of its ability to efficiently transmit electrical signals.
What are 3 conductors?
rubber, Styrofoam, and plastic
Is tantalum metalloid or metal?
Tantalum is a metal, specifically a transition metal. It is known for its high melting point, corrosion resistance, and ability to efficiently store and release electrical energy in capacitors.
What is the permittivity of copper and how does it affect the electrical properties of the material?
The permittivity of copper is approximately 1.0 x 10-11 F/m. This property affects the electrical properties of copper by influencing its ability to store electrical energy and conduct electricity efficiently. Copper's high permittivity allows it to be a good conductor of electricity, making it ideal for use in electrical wiring and circuits.
Does zinc conduct electricity?
Yes, zinc is a good conductor of electricity. It is commonly used in batteries and other electrical applications due to its ability to conduct electricity efficiently.
What is the relationship between the metal reflectivity and its ability to efficiently reflect light?
The relationship between metal reflectivity and its ability to efficiently reflect light is direct. Higher metal reflectivity means the metal is better at reflecting light efficiently.
What are the benefits of using copper conduit in electrical installations?
Copper conduit is preferred in electrical installations due to its durability, resistance to corrosion, and ability to conduct electricity efficiently. It also provides better protection against electromagnetic interference and is easier to work with compared to other materials.
