What is a reflector and what is its purpose in in lighting?
A reflector is a, usually large, sheet of reflective material used to reflect light into shadows of a subject. It is usually used where there is strong lighting from one side to even up the light in an image.
Who is Edelmiro Quibilan?
Edelmiro Quibilan is a Filipino engineer who invented a light reflector assembly ballast (light and heat amplifier) and a smokeless stainless-steel charcoal stove with grill (QB stove).
Explain why the outside cases of electric appliances ususally are made of plastic?
Plastic is a good insulator and a bad conductor of electricity, which makes it a good material to protect people from electric shocks when handling appliances. On top of that, plastics are inexpensive and easy to shape.
What makes a good electrical conductor?
number of electrons capable of freely moving in the outermost shell of an element. eg. Copper
Why is gold used to conduct electricity in plans?
Gold doesn't oxidize or corrode no matter what. Tha makes it a good choice when reilability of an electrical connection is more important than the cost.
Is silver a good reflector?
simply no
Can an object be both a good absorber and good reflector at the same time why or why not?
No, an object cannot be a good absorber and a good reflector at the same time. The properties of absorption and reflection are usually inversely related in materials – a good absorber tends to be a poor reflector and vice versa. This is because the absorbed light energy is converted into heat in good absorbers, whereas reflected light energy is not absorbed.
What it is a good reflector of light?
plane mirror
Is the color black a good reflector?
No, black is not a good reflector of light. It absorbs most of the light that hits it rather than reflecting it, which is why it appears dark.
Is leaf a reflector of light?
i think it is a reflector of light as we are able to see a leaf in the presence of light, it means when light bounces back into our eye, we can see it otherwise we would not be able to see it. however it is not a good reflector of light, but a poor reflector of light.
Why are oil tankers painted silver?
good reflector of heat
What would be a good antonym for the word projector?
reflector or inflector.
Is a good emitter of heat also a good reflector of heat?
Not necessarily. An object can be a good emitter of heat without being a good reflector of heat. The ability to emit and reflect heat depends on different properties of the material, such as surface texture and composition.
What is a good reflector of sound?
A good reflector of sound is a hard and smooth surface, such as concrete, tile, or glass. These surfaces reflect sound waves easily, rather than absorbing them like softer or uneven surfaces.
What is a good reflector of light?
A mirror is a good reflector of light because it has a smooth and highly reflective surface that bounces light rays off at equal angles, resulting in a clear reflection.
Can an object be both a good absorber and good reflector at the same time?
No, an object cannot be a good absorber and a good reflector at the same time. When an object absorbs light well, it does not reflect much of it, and vice versa. The ability of an object to absorb or reflect light depends on its properties and the material it is made of.
Is glass a good reflector of light?
Glass is not a good reflector of light as it allows most of the light to pass through it. A small amount of light may be reflected off the surface of glass, but it is generally transparent and allows light to transmit through it.
