Answer 1

Answer:

S H. M. IS THE CORRECT ANSWER OF YOUR QUESTIONS ABOVE

Answer 2

Option B) Resonance

The heating and cooking of food evenly by microwave oven is an example of: Resonance.

• A device called a magnetron, which is a resonant cavity that causes current to naturally oscillate at high frequency and so release electromagnetic waves, produces the microwaves in a microwave oven. There is no external circuit that is carefully managed that causes the oscillation of the current in the magnetron.
• Every item, even molecules, has a resonance frequency. This means that they vibrate wildly in response to a specific input frequency, much as how a child's swing will generate significant oscillations if pushed at the proper rate.
• Microwave wavelengths range from 30 to 0.03 cm at frequencies between 109 Hz (1 GHz) and 1000 GHz. There are several communication systems applications in this spectral domain that are significant in both the military and civilian fields.
• Resonance can be used, for example, to create a constant frequency state in circuits intended to generate AC signals. For this reason, a parallel (tank) circuit is typically employed, with the capacitor and inductor being directly connected to each other and transferring energy.
