After some researches, its seems like heat can pass through the vacuum as well. The example we can take that the heat waves are coming on the earth by vacuum. And the vacuum is in between the two bodies like earth and sun!

If heat wave doesn't travel through vacuum then how would heat transfer take place like in vacuum evaporator and other vaccum based equipments?

Himanshu said:   8 years ago
Heat travels through vacuum by radiation and its reflection from mirror is also explained by its wave nature (radiation-mode on heat conduction).

Dear friends heat wave can travel in a vacuum. If not then how the Vacuum oven exist?

Dear friends heat wave can travel in vacuum (ex. Radiation). Heat waves traveling path depend on material.

Heat wave can not be reflective by mirror because it heat is a property not material like light which is reflective.

Heat in the former of radiation pass through vacuum that's why heat energy comes from sun, also it is reflected by mirror that is the principle behind polished surface in vacuum flask interior and in the form of radiation heat waves pass in straight line but in conduction the path is defined by shape of the matter.

Can not reflect by mirror thats wave not light.

How heat waves reflected by the mirror. Heat can pass through vacuum ex: vacuum oven.

You see, light is a material in the general sense of the word (it's made of particles), but heat is a property (like color or momentum). Infrared radiation, which *transmits* heat, can indeed be reflected by metallic mirrors.

How tell me how heat transfer by mirror?
