The electrical energy input which is meant to turn the lights on is not 100% used (since no machine is 100% efficient.) Most of this energy is wasted as heat energy.
If a substance reaches a certain temperature it gives off light and heat. When a filament light bulb reaches that temperature, it gives off both light and heat
When electricity passes through the wire of a light bulb, the resistance in the wire causes it to heat up through a process called Joule heating. This heating effect causes the wire to reach such high temperatures that it emits light and produces illumination in the bulb.
answ2. Fire require three things. A source of fuel. Oxygen. And a heat source. Known in the Fire Service as the Fire Triangle.
Refraction occurs when light changes speed as it moves from one medium to another, causing it to change direction. This change in direction can make objects appear distorted or bent when viewed through the refracting medium, such as a lens or water.
the speed of light is 186,000 miles a second it takes the light from the sun takes 7 minuates and 59 seconds to reach earth if the sun explodes it wont be known until the light reaches the earth.
White and black are not colors. They are defined as shades.
A light bulb can make heat and light.
A light bulb converts electrical energy into light energy and heat energy.
Light and heat.
Light+Heat
does the vessel where the light bulb is placed affect the heat
light and heat energy occur in a light bulb when it is turned on.
The energy that goes in is electrical energy; the energy that leaves it is visible light, as well as heat.
The electrical energy was transformed into light and heat energy in the light bulb, causing it to glow. This transformation occurs when the electricity passes through the filament in the bulb, producing light and heat as a result of the filament's resistance to the flow of electricity.
Light and heat.
The light bulb can be controlled on a timer, or simply manually switched on and off. The heat can be controlled by using a thermostat. Some bulbs also provide both light and heat, and by raising the bulb the heat can be approximately controlled.
The heat from a light bulb is primarily radiant heat, which is transferred through electromagnetic waves. Additionally, some heat may be transferred through conduction to the bulb's surroundings.
When the switch is closed, the electrical energy from the power source will flow through the circuit and into the light bulb. The bulb's filament will get hot due to the resistance, producing light and heat. The efficiency of energy conversion into light and heat by the bulb depends on the bulb's design and materials, as well as any losses due to inefficiencies in the circuit.
