I guess red color because of its inherant property of high wavalength n low frequency has high visibility.
Ex : Tall bldgs,towers have red beacons because they have to have :rolleyes: maximum visiblity
Thats my point tooo...see if red is good for vision and also has high visibility,why is it used for military hangars etc where the purpose wud be to hide whtever is taking place...
Checkout the attachment...
thanks
hi all,
I am a Physics Learner and have a following question:
Why do secret military installations like plane hangars etc lighted by 'RED' lamps?Also the CCC rooms have red lights.Isn't it ironic that red color is also used as traffic signal because it is visible for the farthest distance...
