Answer:

Shift a thermometer through one hole and a glass tube with a stopper through another hole. Now, with the help of a vacuum pump, remove the air from the flask and try recording the temperature from the thermometer. Put the flask in the bright sunlight, and we'll see that the thermometer records a temperature rise.

First of all, take a flat bottom flask and fix a rubber stopper having two holes in the mouth of the flask. Shift a thermometer through one hole and a glass tube with stopper through the other hole. Now, with the help of a vacuum pump, remove the air from the flask and try to record the temperature from the thermometer. Put a flask in the bright sunlight and we will observe that the thermometer records a rise in temperature. So, on this basis, we can say that this experiment proves that the heat radiation can travel through vacuum.
