Infrared (IR) imaging can penetrate the layers of paint to reveal underlying sketches and underdrawings because different materials absorb and reflect IR light differently. The carbon-based pigments in the underdrawings, often used in preliminary sketches, absorb IR radiation, making them visible against the less absorbent paint layers. This technique allows conservators and art historians to study an artwork's composition and evolution without damaging the surface. Additionally, IR can help identify changes made by the artist during the painting process.

How does an infra-red camera work?
Infrared (IR) photos are taken with normal cameras using infrared film. The difference is the film used, not the camera. IR film is sensitive to the IR spectrum of light, not the visible spectrum.
What is IR drop?
IR Drop means voltage drop. As voltage drop across any resistance is product of current (I) passing through resistance and resistance value(R ) , it is often written as IR drop.

Why is tsop1738 used in ir receiver?
TSOP1738 is Infrared IR Sensor Receiver used in IR receivers to get signals. This is because it is sensitive to 38 kHz.
Explain glass cell cannot be used for IR region?
Glass absorb IR.
Which component can replace the infrared LED in any electronics circuit?
If a circuit requires an IR LED, it requires an IR LED, there is no replacement. If a circuit does not require an IR LED, there is no need to look for a replacement.
Transparent material for IR?
One common transparent material for infrared (IR) radiation is sapphire, which is often used in IR windows and lenses due to its clarity over a wide range of wavelengths. Other materials, such as germanium and zinc selenide, are also widely used for IR applications due to their transparency in the IR spectrum.
Why is the symbol iridium ir?
Ir comes from the first two characters in iridium.Besides symbol I was already used to represent iodine.
What doe infrared mean?
Infrared (IR) is a type of wave on the Electromagnetic Spectrum. Infrared is also a technology which is most popularly used in remotes. TV remotes use a IR blaster to send IR signals to an IR receiver on the television.
What is the IR Infrared blaster or IR Controller is used to?
An infrared blaster (or IR blaster) is a device that emulates an infrared remote control to autonomously control a device that is normally controlled only by remote control key presses.IR Blaster is used to change the channel .

Why polystyrene film is used for IR calibration?
Polystyrene film is used for IR calibration because it has known peaks and absorbance patterns in the infrared region, making it a reliable reference material for calibrating IR spectrophotometers. Its stable properties and well-defined spectrum help in accurately calibrating the instrument for precise measurements of other samples.
What is transistor BC557?
it is a transistor used in IR TOGGLE SWITCH. :-)
What radiation is used for digital camera?

Why kBr is used for IR?
KBr is used mostly in IR Spectroscopy techniques because it do not absorbs moisture at room temperature as compared to NaCl. More over it do not give its own peak.
