What is the difference between concrete and material noun?
The main difference between concrete and material noun. Concrete are those noun which we can feel with five sense organ. Material are those from which other things are made. Every material noun can be concrete. But every concrete can't be material.
What is nanotechnology used in?
suncream the one that doesn't leave white marks. it has titanium dioxide and zinc oxide in the cream these two reflect uv rays but absorb visible light they are so small that they are invisible and leave no white marks
What is the purpose of a LED in a circuit?
An LED, or light emiting diode, can have many functions. Commonly used as a solid state light emitter, LEDs of nearly any color of light are available, including ultraviolet and infrared.A less obvious use of a light emitting diode is to detect light. A LED makes a very efficent and narrow band light detector. It will produce electric current in response to light that is about the same wavelength (and therefore color) as when it is used as an emitter.Another use of an LED is to make a fairly stable voltage reference; A red LED when forward biased will have a steady voltage drop of about 1.8 volts, an orange LED produces a voltage drop of about 2.0 volts, and about 3.5 volts for blue and white emitting LEDs.LEDs can be used as modulated light emitters to transmit speech, music and digital information. A good example is a television remote control which digitally pulses a infrared LED to change channels, control volume, and so on.LEDs are used in solid state switches when optically coupled to a photodiode or photo resistor. LED flashlights are very common, and some small light bulb replacements are available, with larger bulb replacements soon to come. Some links are provided below:
What is the brightest light emitting diode?
L.E.D or light emitting diode A light-emitting diode (LED) is a semiconductor light source.[3] LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962,[4] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness
What types of bulbs used for street lighting?
You may use electronic bulb of any kind in your street. It is entirely depends upon your choice but the main thing you should keep in mind that their light should be of white color like tube light. Because it will be more difficult to see things in some other color other then the white one.
What colors combine to create white light?
Red, green, and blue light combine to create white light.
How can I create white light?
To create white light, you can combine all the colors of the visible spectrum together. This can be achieved by using a white light source, such as a light bulb or the sun, which emits a combination of all colors. Alternatively, you can use a prism to break white light into its component colors and then recombine them to create white light again.
What happens to white light if it goes through a colored transparent material?
When white light passes through a colored transparent material, the material will absorb some wavelengths of light and transmit others. The transmitted light will appear to be the color of the material, as it is primarily made up of the wavelengths that were not absorbed by the material.
Why is a light bulb white?
A light bulb appears white when it emits light across the full visible spectrum, combining all colors to create white light. This is achieved by using a combination of phosphors to produce a balanced spectrum, or by using multiple LEDs of different colors that blend to create white light.
Why does a sheet of paper appear white?
A sheet of paper appears white because it reflects most of the light that hits it. The material that makes up the paper scatters the light in different directions, giving it a white appearance to our eyes.
Why do we see white when all colors of light are combined?
When all colors of light are combined, they create white light because white light is a mixture of all the colors in the visible spectrum.
What color do green and magenta light make?
Green and magenta light combine to create white light.
Which colour material reflects all light and absorbs none?
White
What colors create white light?
White light is created by combining all the colors of the visible spectrum: red, orange, yellow, green, blue, indigo, and violet. When these colors are combined in equal amounts, they create white light.
What colors mix with white?
Colors that can mix with white to create lighter shades include pastel colors such as light pink, light blue, and light yellow. Mixing these colors with white can create softer and more subtle hues.
What color does blue and white create when mixed?
light blue - it depends on how much white you use.
What color does blue and white create mixed?
light blue - it depends on how much white you use.
