So we were studying about different types of heat transfers, conduction, convection, and finally we learned about radiation, it was sort of confusing, so I am going to write stuff, and hopefully someone can see what i wrote and see if its correct.
basically the book says
'Radiation
Energy from the sun is transferred through the vacuum of space, without being carried by particles, in the form of radiation. In cases like this, hot objects lose thermal energy by emitting electromagnetic waves. Sometimes these electromagnetic waves are visible and the objects glow brightly like the sun or like very hot metal. At other times warm objects emit non visible forms of electromagnetic radiation, such as microwaves, infrared waves and x rays. Usually hot objects lose heat due to infrared rays. This process is sometimes called heat radiation. '
and what i got from that is
-Light is a form of electromagnetic wave
-not all forms of electromagnetic waves are visible
-All electromagnetic waves are radiation?
- Thermal energy is transferred from heat to radiant energy(or radiation)
