AaSpelling

r·a·r·e·f·a·c·t·i·o·n

With an e after rar- (not 'rarifaction'), just as in rarefy and rarefied.

Spelling r-a-r-e-f-a-c-t-i-o-n है, जिसमें rar- के बाद e आता है ('rarifaction' गलत है), ठीक rarefy और rarefied की तरह।

General knowledge

In a longitudinal wave such as sound, the regions where particles are close together are compressions and the regions where they are spread out are rarefactions.

ध्वनि जैसी अनुदैर्ध्य तरंग में जहाँ कण पास-पास होते हैं उसे compression (संपीडन) और जहाँ दूर-दूर होते हैं उसे rarefaction (विरलन) कहते हैं।
