Answer:
Microwave is used to heat the food and uses a different form of electromagnetic radiation. The form of electromagnetic radiation used in microwaves are radio waves and infrared radiation.
The frequency of such electromagnetic waves is 2,450 megahertz (2.45 gigahertz) and the wavelength range is approximately of 30 cm (frequency = 1 GHz) to 1 mm (300 GHz).
<u>Microwaves or electromagnetic radiation produced by a magnetron, an electron tube in the microwave. The cavity of the magnetron cavity magnetron produces electromagnetic waves defined wavelength. Electromagnetic radiation strikes within the metals in the microwave and is absorbed by food. Electromagnetic radiation allows the vibration of water molecules in the food and makes the food hot.</u>
Explanation:
The given data is as follows.
Electric field (E) = 
Charge (e) = 
C
Formula to calculate the magnitude of force is as follows.
F = qE
= 
= 
Therefore, we can conclude that magnitude of the force on a calcium ion with charge +e is .
The amplitude of wave-c is 1 meter.
The speed of all of the waves is (12meters/2sec)= 6 m/s.
The period of wave-a is 1/2 second.
