The term "black body," as related to "black body radiation," is a hold-over from the study of such light during the 1800s. BBR is emitted from any object that has a temperature. Such an object can be of any color.
It's one of the colour. Black colour absorb all colour. A perfect black body radiates heat.
The colour black absorbs all other colours. Thus green won't be reflected, it will be absorbed by a black body.
The Black mamba isn't actually black ! It's body is a beautiful olive-green colour all over. The 'black' comes from the lining of the inside of the snake's mouth. The tissues are jet black in colour.
Because that's exactly what its colour is... A sandy-coloured body with a black head.
Black is not a colour though.
Black or Blue-ish Black
Emissivity of the black body is 1. And this is probably the reason that the condenser of refrigerator is painted black to loose heat efficiently by radiation ,though there are other modes of heat transfer like conduction and convection which is not affected by colour of the body
Older cars often had chromium plated bumpers (fenders) more modern cars tend to have either black bumpers or bumpers which are the same colour as the main body of the car (body colour bumpers).
the brown or black color given to the body is through a pigment known as melanin
People sweat to reduce their body temperature. It doesn't matter what colour you are, if your body is too hot, you sweat!
the black colour absorbs all the colour and reflects nothing.this is why it appears black in colour. :) lillyXOXO
Black opal can be very expensive, only low grade black opal is sold by kilo weight. This low grade is called potch and colour which means that maybe bit of colour might be in this rough black opal I have seen parcels sold for $200 per kilo but it has no colour. Good kilo bucket of rough black opal would cost around $5,000 .00 Black opal is rated by body tone N1 for deep black colour, and N4 for light black colour. So for $5000 per kilo, dont expect N1 body tone. Black opal is sold by carat, and rare patterns are worth $5,000 to $20,000 per carat; especially red fire harlequin pattern n1 body tone, and over brighness rating of 4.
