No @Prakhash Danraj.
Abroptivity means --> transmitivity , reflexectivity =0
Then, abroptivity+reflexectivity+transmitivity=1. Right?

If absorptivity=1 means emmisivity=0 right,
Since absorptivity+emmisivity+transmittivity=1.
Please explain.
Since absorptivity+emmisivity+transmittivity=1.

Kirchoff's identity.
States on,
Absorptivity = Emissivity.
States on,
Absorptivity = Emissivity.

According to kirchoff's law, an ideal black body is the one which absorbs all the radiation incident on it, hence its absorptivity is 1.
