SHOULD WE CONSIDER MIRRORS AS "PERFECT BLACK BODY"?

WELL, WE CONSIDER A BODY AS PERFECTLY BLACK WHEN IT ABSORBS ALL THE RADIATION. BUT, THE PERFECT BODY's PROPERTY IS THAT IT EMITS THE SAME AMOUNT OF RADIATION ALSO MUCH IT ABSORBS!!!!

 

SO, WOULD IT BE O.K. FOR US TO CALL THE MIRRORS, THE PERFECT BLACK BODY???

 

WHAT ABOUT YOUR OPENION? THE MIRROR EMITTS ALL THE RADIATION IT ABSORBS....

 

RESPOND TO ME AS SOON AS POSSIBLE YOU THERE.

THANKS.

gaurav u r a little mistaken

the body gets the colour by reflecting the light not by emmiting it.

the black body absorbs all the seven colours which constitutes the white light thus appearing black.

thus it would not be appropriate to call the mirror a perfect black body.

everything whithout the light to illuminate would be a blackbody.

try to see urself in a mirror in a perfectly dark room.

the white light has seven colours

voilet

indigo

blue

green

yellow

orange

red

thus we see plants green because when white light falls on them they absorb all the colors reflecting the green.that's why they appear black in the absence of white light(at night)

i hope this explains ur query.
