Infrared radiation

Electromagnetic ko infrared radiation maida hankali ne akan wani na yankin tsakanin electromagnetic kalaman, wanda ganin mutum ido da kuma ta ja tip da obin na lantarki ko obin na lantarki radiation. A babban bambanci a cikin Tantancewar kaddarorin abubuwa lura tsakanin tsinkaye a cikin infrared da bayyane haske. Alal misali, don short-hare infrared radiation a ruwa da dama santimita m opaque.

Game da 50% na hasken rana radiation da dama a kan irin wannan. Yana da wani ɓangare na HID da kuma Iskar Wutar fitilu, kazalika da wasu lasers iya emitting infrared radiation. Don yin rijista da shi, ta amfani photovoltaic kuma thermal karba ko musamman hotunan.

A cikin kewayon na infrared radiation yana da uku aka gyara: short-kalaman, matsakaici-kalaman da dogon-kalaman yankin. Ƙara wavelengths kasu kashi sublimated ko terahertz radiation.

Human fata ta ji tsoron infrared radiation daga zafi abubuwa, kamar yadda da thermal abin mamaki, don haka ne ma ya kira "zãfi." A zango radiated zafi, ya dogara a kan dumama zazzabi. Idan zafin jiki ne m, da zango ne takaice, da kuma tsanani da ta watsi sama. The m ions da kwayoyin halitta emit infrared radiation. A wannan fanni, a gwada low yanayin zafi da kuma shi ne electromagnetic radiation bakan blackbody.

Falakin William Herschel gano electromagnetic radiation a 1800, bayan da infrared haske an yi karatu a daki-daki. Da kaddarorin Herschel m amfani da thermometers. A sakamakon gwaje-gwajen, an nuna cewa daban-daban rabo daga cikin bayyane bakan zazzabi ayyukan daban. Herschel ya gano wadannan: matsakaicin zafi, wanda ya ta'allaka ne a waje da cikakken ja launi, yana yiwuwa kuma shi bayyane refraction.

Modern awon kafofin na infrared radiation su ne bisa m-jihar kwayoyin gas lasers. Su ne daidaitacce da kuma ajali watsi mita.

Don yin rijista thermal radiation musamman na daukar hoto faranti amfani. Photoresistor photoelectric injimin gano illa da da yawa fadi kewayon ji na ƙwarai.

Yana yana da m ikon infrared radiation. Da kaddarorin ne irin wannan cewa za a iya amfani da a fannoni daban daban:

• magani - a physiotherapy.
• sterilization kayayyakin abinci ga disinfection.
• ramut - a talabijin m controls, atomatik kuma tsaro tsarin, wasu model na wayoyin hannu.
• zanen - ciyar da makamashi da kuma kudi ne sosai ƙananan fiye da convection Hanyar.
• a matsayin anti-lalata wakili.
• masana'antun sarrafa kayayyakin abinci - electromagnetic taguwar ruwa wani fanni da thermal da kuma nazarin halittu tasiri a kan samfurin, wanda taimaka hanzarta biochemical canje a biopolymers.
• m masana'antu.
• sarari dumama tituna ko gidaje ga babban da kuma ƙarin dumama.
• dubawa da amincin kudi, da dai sauransu

Infrared radiation zai iya sa lalacewar mutum idanu. A waɗannan wurare inda akwai high zafi, infrared radiation iya zama haɗari ga ido, kuma idan ta ya ba tare da wani bayyane haske Madogararsa. A cikin wadannan lokuta da shi wajibi ne don amfani da m fitattun idanu.

A wasu lokuta, infrared radiation hanyar cutar da mutane ba zasu iya ba. Yana da cikakken aminci da ba shi da wani abu kama da ultraviolet ko X-haskoki.

Infrared radiation, amfani da dafa abinci, yin abinci ne sosai dadi, kamar yadda har yanzu akwai duk da ma'adanai da kuma bitamin, da obin na lantarki, shi ba shi da wani abu da ya yi.

A general mu iya cewa kusan babu wani daga cikin wuraren da infrared radiation ba a amfani da yau.
