Is a hair dryer an example of radiation?

They all have something to do with heat.) Explain the three types of heat tranfer to the students. As a class, decide which item is an example of each type of heat transfer. (Blow dryer- convection, curling iron-conduction, cookie or bread-baked by radiation.)

Similarly, which is an example of radiation?

A good example would be heating a tin can of water using a Bunsen burner. Initially the flame produces radiation which heats the tin can. The tin can then transfers heat to the water through conduction. The hot water then rises to the top, in the convection process.

Why is a microwave an example of radiation?

Microwave ovens work by using very high levels of a certain frequency of RF radiation (in the microwave spectrum) to heat foods. When microwaves are absorbed by food containing water, it causes the water molecules to vibrate, which produces heat.
