What else can I help you with?
What does Infrared Penetrate?
Infrared light can penetrate into the skin and tissues, reaching depths of up to several millimeters. It can help with improving circulation, reducing inflammation, and relieving pain in the targeted area.
What does infrared wave mean?
Infrared waves are a type of electromagnetic radiation with longer wavelengths than visible light. They are commonly used in technology such as night vision devices and remote controls because they can penetrate smoke, fog, and haze. Infrared waves are also emitted by all objects with a temperature above absolute zero.
What sort of radiation absorbs or reflect radiation?
It doesn't absorb clever. It penetrates, and it can penetrate paper, smoke, a layer of skin and thin aluminium.
What form of electromagnetic waves are used in smoke detectors?
There are two types of smoke detectors:Alpha particle - these do not use electromagnetic wavesPhotoelectric - these use a beam of either visible lightor near infrared electromagnetic waves
Is the radiation in smoke detectors harmful?
The radiation in smoke detectors, usually in the form of ionizing radiation from americium-241, is very low and not harmful to humans under normal conditions. The radiation level from smoke detectors is well within safety limits set by regulatory agencies.

How can satellites see through clouds and smoke?
Satellites equipped with synthetic aperture radar (SAR) sensors can penetrate clouds and smoke by emitting their own microwave signals that can pass through these obstacles and reflect off of the Earth's surface. By analyzing the return signal, satellites can create images of the ground beneath the clouds or smoke. Additionally, satellites with thermal infrared sensors can detect temperature differences caused by fires or heat sources even through clouds or smoke.

What type of radiation is in smoke alarm?
alpha radiation

Can led light passes through the dense smoke?
Yes, LED lights can penetrate dense smoke to some extent, but the visibility will be significantly reduced compared to clear air. The light may scatter and disperse within the smoke particles, making it harder to see clearly.
Why is thermal imaging useful?
Thermal infrared cameras are used for many things. Examples of this are with firefighters. Firefighters use these cameras to see through smoke and possibly through walls. Also, police officers may use these cameras to seek out running criminals in the dark. People interested in the supernatural may additionally use thermal infrared cameras as it can help to see paranormal apparitions.
What use is alpha radiation?
It is used in smoke detectors as it cannot travel far in air. Alpha radiation is emitted and as long as the detector in the device is receiving the alpha radiation, then no smoke is present. When smoke particles are present, they interrupt the radiation, and so the detector doesn't pick up the radiation, causing the alarm to go off.
How do firemen use infrared goggles?
Infrared goggles are used when someone calls and reports the smell of smoke in the house. When they arrive and do not see any visible smoke, they will use the infrared gear to see through the walls to look for hot spots. Fire fighters now use infrared technology to find victims in smoke-filled spaces. The new equipment cannot be worn on the head because breathing apparatus will be in the way. These hand-held devices quickly and effectively detect people in spaces where there is limited visibility because of their sensitivity to differences in temperature. The equipment can also be used as described above.
How are infrared waves helpful to humans?
Infrared waves are helpful to humans because they are used in various applications such as thermal imaging, night vision technology, remote controls, and infrared saunas. They can penetrate fog, dust, and smoke, making them useful in security systems and search and rescue operations. Additionally, they are also used in medical imaging to diagnose and monitor certain conditions.
