What are some ways in which materials affect how light is transmitted?
How much light a material absorbs or lets through depends mainly on what kind of material it is. Usually pure substances will not absorb light but rather lets light through or reflects light. Exceptions include carbon, uranium and others. The exact theory goes into detail in how electrons absorb that energy and move to a higher orbital but generally, a material will let light through if the electrons require excessive energy to jump to a higher orbital.
What kind of motor is used in ceiling fan?
electric
What kind of material is inside the holes in the outlet?
Do that
How do electric rays generate electricity?
The wiring inside the light bulb is very thin (the filament) and glows when heated. The current through the thin wire heats up the filament wire so that it will glow. See the related link 'How Light Bulbs Work'.
What kind of metals are present in a doorknob?
This depends on the kind of doorknob: which material? wood, plastic, Bakelite
What kind of light was invented in France in 1909?
electric light
What kind of light bulb did Thomas Edison invent?
Thomas Edison invented the Incandescent electric light.
What kind of energy does an electric motor change into kinetic energy?
Electrical energy.
What kind of change occurs when you light a fire. A physical change or chemical change?
Both !
What happens when light moves form one kind of matter to another?
When light moves from one kind of matter to another, it can be reflected, transmitted, or absorbed depending on the properties of the materials involved. The change in medium can also cause the light to change direction and/or speed, which is known as refraction. Additionally, the color and wavelength of the light may be affected by the interaction with the new material.
What kind of material lines the tubes of fluorescent lights and glows when exposed to UV light?
Phosphor is the material that lines the tubes of fluorescent lights and glows when exposed to UV light. This material emits visible light when excited by ultraviolet radiation.
What kind of light did Edmund Hillary use candle oil lamp or electric?
oil lamp
Is a light bulb is a kind of lever?
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
When you turn on a lamp electric energy changes to what kind of energy?
When you turn on a lamp, electric energy is converted into light energy and heat energy. The electric current flowing through the lamp's filament generates heat, which in turn produces light.
If you turn on and off a light what kind of change would it be?
switch
