Infrared (IR) light is used by electrical heaters, cookers for cooking food , short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.
How are infrared waves used in your home?

What are some applications of infrared waves?
Infrared radiation can be used as a deliberate heating source . For example, it is used in infrared saunas to heat the occupants. It may also be used in other heating applications, such as to remove ice from the wings of aircraft (de-icing). Infrared radiation is used in cooking, known as broiling or grilling.
How can infrared waves be used in the future?
Industry. There are various industries that currently use infrared technology to their advantage. Astronomers use it to map galaxies far out of reach of the human eye; massage therapists use it to warm the skin and directly relax the muscles; it can be used in the transmission of data between devices.
What are 5 uses of infrared waves?

What are the dangers of infrared waves?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens . Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.
What are examples of infrared?
The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared. The temperature-sensitive nerve endings in our skin can detect the difference between inside body temperature and outside skin temperature.
How do you detect infrared?
The simplest way to view infrared light is by using a remote control while looking through a camera , but you can also make infrared goggles by yourself. Before you know it, you’ll be able to see infrared light for yourself!
Are heat and infrared the same?
Infrared is radiated heat: the feeling of warmth from the sun on your face; the heat from a coal fire, or a toaster. It is even the same form of heat emitted by your own body . ... Infrared waves travel through the air and when they touch a surface, heat energy is released regardless of the surrounding air temperature.
What color is infrared?
The invisible near infrared light of CIR can be “seen” by shifting it and the primary colors over as shown at left. Near infrared wavelengths become visible as red while red wavelengths appear as green and green as blue.
How are infrared waves created?
Earth scientists study infrared as the thermal emission (or heat) from our planet. As incident solar radiation hits Earth, some of this energy is absorbed by the atmosphere and the surface , thereby warming the planet. This heat is emitted from Earth in the form of infrared radiation.
What is an example of infrared radiation?
Even objects that we think of as being very cold, such as an ice cube, emit infrared. ... For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits.
Can humans see infrared?
The human eye can detect the visible spectrum of the electromagnetic spectrum — a range of wavelengths between 390 to 700 nanometers. ... Louis discovered that contrary to prior beliefs, the human eye is in fact capable of seeing infrared light — but only under certain conditions.
What does infrared do to the body?
Infrared therapy has many roles in the human body. These include detoxification, pain relief , reduction of muscle tension, relaxation, improved circulation, weight loss, skin purification, lowered side effects of diabetes, boosting of the immune system and lowering of blood pressure.
What does infrared light do to the body?
Unlike ultraviolet light – which has damaging effects upon the tissues and cells of the body – infrared light helps cells regenerate or repair themselves . Infrared light also improves the circulation of oxygen-rich blood in the body, promoting faster healing of deep tissues and relieving pain.
Does infrared light help wrinkles?
Research shows that red and infrared light therapy can significantly improve skin complexion, reduce fine lines and wrinkles , and increase collagen density.
