Question

Shiny and smooth surface are good reflectors of heat then why does glass get heated quickly​

Answer 1

Answer:

Here is the spirit

Explanation:

Surfaces designed to reflect a broad spectrum of electro-magentic waves, (shiny things generally, like mirrors or polished metal) specifically infrared wavelengths are good reflectors of radiant heat.

Think of the reflective pads put in car windshields or in large scale commercial freezers as examples.

In some conditions, (as in the commercial freezer example above) there are other modes of heat transfer (conduction and or convection) to be taken into account.

For example, a highly polished piece of aluminum will be a good reflector of radiant heat, but is still capable of conducting heat applied through direct contact.

Gold is the best material for reflecting radiant heat.

The engine bay of the McLaren F1 (not to be confused with the MP4 series of cars produced for Formula 1 racing) was lined with gold for this reason. ( that and the fact that owning a car with gold in the engine bay sounds kinda pimp and that’s what the company was going for. )
