There is a very definite frequency band specified in which microwave ovens must operate.

The label inside the one in my kitchen reads: " 2450 MHz "

Wavelength = speed/frequency = 12.24 centimeters

Radiators transfer heat by electromagnetic waves. The sun waves/rays send electromagnetic waves.


Are heat waves electromagnetic waves?

Heat waves are the same as infra-red radiation; however it is the more specific name. Electromagnetic waves range from Radio Waves to Gamma Rays so, technically, the answer is no.


Are heat waves transverse or longitudinal?

No. Radiant heat is an electromagnetic wave, and EM waves are transverse waves.


Which type of waves from the electromagnetic spectrum are used in heat lamps and heating sensing devices?

Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.

Does energy dissipate from electromagnetic waves?

Electromagnetic waves do produce heat. It depends a bit on the frequency and of course the strength of them as to how much heat that is produced. It also depends on what medium the waves travel through. Example: A microwave oven heats up the food by interacting with water molecules, making them vibrate. This vibration causes friction and friction turns into heat. This is done via electromagnetic waves. These waves are not absorbed by glass or pottery, hence they stay cold.


What type of electromagnetic wave would a restaurant owner be interested in?

-- Microwaves (to heat food). -- Radio waves (to entertain customers). -- Light waves make it possible for customers to read the menu and to see what they are eating. -- In some primitive, backward restaurants, 'heat' waves are still used to heat food.
