Does Concrete absorbs visible light and re-radiates it as infrared energy?
Concrete absorbs visible light and re-radiates it as infrared energy
What EM waves are emitted by fire?
Light (visible) and heat (infrared)
What is the visible smoke emitted from burning wood called?
Particulate Matter.....
Is alpha particle visible or invisible?
Visible, provided you have an extraordinarily high power electron microscope.
Explain how photoelectric effect confirms particle nature of radation?
The photoelectric effect is a quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x-rays or visible light.
How does fluorescent work?
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.

What part of an image intensification tube converts the X-ray image into a visible image?
Input Phosphor. The x-ray image intensifier converts the transmitted x rays into a brightened, visible light image. Within an image intensifier, the input phosphor converts the x-ray photons to light photons, which are then converted to photoelectrons within the photocathode. The electrons are accelerated and focused by a series of electrodes striking the output phosphor, which converts the accelerated electrons into light photons that may be captured by various imaging devices.
Is alpha particle visible or invisible?
Visible, provided you have an extraordinarily high power electron microscope.
The wavelengths of radiation emitted by Earth are?
they are longer than those emitted by the sun.
Why cathode dark space is dark?
Because it absorbs visible light.
How can visible light interact with matter?
The matter absorbs or reflects the light.
Why light emitted by a bulb is yellowish in colour but from a fluroscent tube is white?
You are seeing the spectrum of the metal used in a light bulb. In a florescent tube you are seeing ultraviolet light being transformed into visible light by the internal phosphor coating.
Can you see a 200 micron particle?
A 20 micron particle is not visible with the naked eye. The smallest particle visible to the naked eye is 40 microns. To give you some perspective, a piece of hair's width can range from 40 to 120 microns.
