इनमें से कौन सी सतह ऊष्मा विकिरण का सबसे अच्छा अवशोषक है?

Dull black surfaces are the best absorbers of heat radiation. They absorb almost all incident radiation and reflect very little.
In contrast, shiny or white surfaces reflect most radiation and absorb very little. That’s why solar panels and cooking pots are often black.
