Hello Stemsocial Community! Welcome to my blog. Nowadays I'm learning different cooking skills from our chef. Today I moved into the Kitchen to cook my favorite dish. After putting all the ingredients according to the recipe of the dish, I kept it in the Electric Oven. After a few minutes, my dish was ready to eat. Is it magic that there was no need for burning fire but your food is cooked in a few minutes? No, it is not magic. It involved one most famous Physical Phenomena that I shall explain today. If you are fired from smoke during cooking and want your eyes will remain safe during cooking then be with me to understand the facts of a microwave oven that involves modern cooking systems as compared to traditional cooking.

Resonance

---

The Phenomenon in which the natural frequency of an oscillating system becomes equal to the resonating frequency of another object that disturbs it is called Resonance. At resonance, the process of energy absorption becomes maximum. The matching frequency results in high amplitude. There are many Examples of resonance in our environment.

• Tuning of Radio
• Sympathetic Vibrations of the Pendulum
• Striking of Drum by Drumsticks
• Vibrations in Turning Fork
• Cooking in Oven

These are a few examples in which we can observe the process of resonance easily. This natural Marvelous has benefits as well as causes big problems in the world.

How is the Food cooked in the electric microwave oven in the absence of fire?

---

Electric Oven works on the principle of Resonance. The oven has a resonant cavity. This cavity emits electromagnetic radiation when the oven is switched on, electric current passes through the oven. It converts this current into electromagnetic Radiation. These radiations pass through the uncooked food. This radiation strikes water molecules in the uncooked food and water molecules start vibrations.

When the frequency by the vibration of water molecules becomes equal to the natural frequency of microwave then resonance is produced. Due to resonance, the process of heat absorption becomes maximum. In this way, the food we have kept in the microwave oven cooked easily without burning of fire. The resonance didn't affect the Quality of food. It is a good way to save ourselves from smoke during cooking.

Warming

The process of resonance can be very dangerous. Its increased amplitude sometimes causes big trouble for us. For example, the marching of the soldiers on a bridge can bring cracking on it due to resonance. The rhythmicity in the movement of a soldier's footwork produces a frequency. When this frequency becomes equal to the natural frequency of the bridge. It will be hard to save this bridge.

Conclusion

---

The process of energy absorption can be increased by Resonance. It looked magical especially when we faced it first time. I have witnessed the process of resonance in many things. From the school level, I have applied it in simple as well as complex ways after watching many YouTube Videos. You can enjoy and watch the process of Resonance in the following video.
