|---|---|---|---|
| 설명 | 파장이 가시광선보다 길며 극초단파보다 짧은 750μm~1mm의 전자파. 눈으로는 볼 수 없고 일반적으로 공기 가운데에서 산란되기 어려우며, 가시광선보다 투과력이 강하다. 사진 적외선-근적외선-원적외선 따위로 나눌 수 있는데, 단파장 부분에는 사진 작용-형광 작용-광전 작용이 있어, 적외선 사진이나 적외선 통신-물질 감정-의료 따위에 이용한다. 1800년에 허셀이 발견되었다. 적외선은 물질에 부딛치며 구성분자의 열운동을 일으켜서 열효과를 주게되므로 열선이라고도 불린다. 태양광선의 약 52%는 적외선이다. 700~800nm의 적외선은 인체피부를 투과해서 피하에까지 이른다. 과도의 적외선 조사는 피부에 온열성홍반을 일으키게 해서 화상을 일으킬 수 있다. |
