3 Types of Infrared heat
- Short Wave (Or Near Infrared, or IR-A). 0.78 to 1.5 microns: covers the thousands to high hundreds of degrees Centigrade.
- Medium Wave (Or Medium or Middle Infrared, or IR-B).
- Longwave Infrared (Or Far Infrared, or IR-C).

How many types of infrared radiation are there?
Infrared is usually divided into 3 spectral regions: near, mid and far-infrared.
What are 3 sources of infrared radiation?
IR is categorized as IR-A (780 nm-1.4 µm), IR-B (1.4-3 µm) and IR-C, also known as far-IR (3 µm-1 mm). Common natural sources are solar radiation and fire. Common artificial sources include heating devices, and infrared lamps used and in the home and in infrared saunas for health purposes.
What are 3 uses of infrared radiation?
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.
What’s an example of infrared radiation?
Since the primary source of infrared radiation is heat or thermal radiation, any object which has a temperature radiates in the 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.
What is the difference between infrared and near infrared?
Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. “Near infrared” light is closest in wavelength to visible light and “far infrared” is closer to the microwave region of the electromagnetic spectrum.
What type of heat is infrared?
Infrared heating is the transfer of thermal energy in the form of electromagnetic waves. True infrared heat should have one common characteristic: that the transfer of heat is emitted or radiated from the heated object or substance. The source emits radiation at a peak wavelength towards an object.
What color is infrared light?
Near infrared wavelengths become visible as red while red wavelengths appear as green and green as blue. Blue wavelengths are shifted out of the visible portion of the spectrum and so they appear as black.
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 are radioactive waves?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. Many of the naturally occurring radioactive materials in the earth, like uranium and thorium, emit alpha particles.
What are infrared waves Class 12?
- Infrared waves often known as heat waves as they are produced by hot bodies.
- Their wavelength is lesser than both radio and micro waves.
- They readily get absorbed by water.
What are the uses of the 7 electromagnetic waves?
What are the 7 types of electromagnetic waves and their uses
- Radio waves: Communication.
- Microwaves: Heating and data transmission.
- Infrared waves: Used in remote control and imaging applications.
- Visible light: Help us see everything around us.
- Ultraviolet Waves: Useful in the study of galaxies.
What are the characteristics of infrared radiation?
Characteristics of Infrared Radiation
- Infrared radiation consists of heat-inducing property.
- The origin is from an alteration in electron movement.
- Wavelength range from 710 nm to 1 mm.
- Frequency range from 430 THz to 300 GHz.
- Infrared radiation is a Transverse wave.
- Speed is 3X 108 m/s.
What do all types of electromagnetic radiation have in common?
All electromagnetic waves have two wavefronts, which are an oscillating electric field and an oscillating magnetic field.
Do humans emit infrared radiation?
Yes, all objects, including human bodies, emit electromagnetic radiation. The wavelength of radiation emitted depends on the temperature of the objects. Most of the radiation emitted by human body is in the infrared region, mainly at the wavelength of 12 micron.
Are microwaves a type of infrared wave?
Microwaves are a type of infrared wave. Radio waves, microwaves, and ultraviolet waves all have longer wavelengths than visible light.
