All correct except for microwaves: Microwave ovens don't use radiation! Radiation is how the sun's energy reaches us. It consists of a ray or beam of electromagnetic particles that travel across any space to heat up any surface they cannot pass through. The heat then conducts from the surface to the core of the mass. Microwaves on the other hand subject the mass to a high frequency (2.4Ghz in India) alternating electric field. Thus making polar molecules in the water align and realign to the changing polarity of the field at that frequency. This causes friction between the molecules and they hole mass heats up at the same time from core to surface. This phenomenon is called volumetric heating. The tendency of any mass to heat up in such field is called it's dielectric loss. This is why microwave heating is so much faster and does not destroy micronutrients.
It’s a medium of cooking. A way to provide heat. What you put in it makes it healthy/unhealthy. If you put broccoli in a microwave and broccoli with half a cup of oil in the over, the microwave one will be healthier.
All convection methods use conduction too. Your statement about oil and water cooking food through convection and not conduction is not technically wrong but not very accurate.
@@thegreedyone8551for what? ..u can buy anything based on budgut and family size becoz studied said that magnetic heat prom convention can not affect much..negligible
