Answer 1

Explanation:

Nonmetallic and nontransparent objects are generally good radiators with an emissivity > 80 %. The emissivity of metals can vary between 5% and 90 %. Shiny, highly reflective metal surfaces will have lower emissivities.

Answer 2

Hiiii Suresh !!!

Low emmisivity means that have low radian

the example of low emmisivity is opaque

Thank u

Hope it helps
