What does fluorescent material do when exposed to ultraviolet radiation?
Fluorescent material absorbs ultraviolet radiation and re-emits it at longer visible wavelengths, producing a glowing effect. This phenomenon is called fluorescence, where the material appears to radiate light of a different color than the ultraviolet light initially absorbed.
What is the effect of radiation and light absorption and reflection?
Radiation absorption occurs when energy from radiation is transferred to a material, causing it to heat up. Reflection of light happens when light waves bounce off a surface rather than passing through it. These processes can have various effects depending on the material and the intensity of the radiation or light.
The sun gives off a large amount of energy in the form of what kind of radiation?
The sun gives off a large amount of energy in the form of electromagnetic radiation, which includes visible light, ultraviolet light, and infrared radiation.
Why does a light bulb give off radiation?
A light bulb gives off radiation in the form of light when the filament inside it heats up to a high temperature, causing it to glow and emit electromagnetic radiation in the visible spectrum. This radiation is what we perceive as light.
What is radiation current?
Radiation current is the flow of electric current due to electromagnetic radiation interacting with a material. When radiation, such as light or radio waves, strikes a material, it can induce the movement of charged particles within the material, resulting in a current flow. Radiation current is important in areas such as solar cells and detectors for measuring radiation levels.
What is transmitted radiation?
Transmitted radiation refers to the portion of radiation that passes through a material without being absorbed or scattered. This can include various types of radiation such as light, x-rays, or gamma rays. The amount of transmitted radiation depends on the material's composition and thickness.
Did the light from the hiroshima bomb blind people?
Yes they were. See the nuclear explosion gives off radiation. you could get blind by the light, or radiation, radiation is energy transmitted in rays. So yes.
What is the name given to a material that gives off electrons when light strikes it?
The material is called a photoemissive material.
What is a material that light cannot travel through?
One example of a material that light cannot travel through is a thick wall made of lead. Lead is a dense material that absorbs and blocks light, preventing it from passing through. This property makes lead commonly used as a shielding material in radiation protection.
What is a light yield?
Light yield refers to the amount of light produced in a scintillator material per unit of energy deposited in it. It is used to measure the efficiency of a material in converting energy into light, which is crucial in applications such as radiation detection and medical imaging. A higher light yield indicates better performance in detecting and measuring radiation.
What esle does the Sun give off besides heat and light?
it gives off radiation
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.
