if an object absorbs light then why it will transmit it in dark and where it gone?

Dear Student

 

All bodies absorb heat or thermal radiations from the environment & simultaneously emit them.

 

A body in the state of losing heat or cooling down will emit more than absorb.

A body in the state of gaining heat or heating up will emit less & absorb more.

 

So while heating up a body, it will keep on absorbing more & more heat radiations.

While the same body is cooled it emits/reradiates the same heat radiations back to the environment.

 

For more detailed overview of therma radiations, pls go thru the detailed content given in the web page given below.

We hope that clarifies your query.
