Microwave radition is part of the electromagnetic spectrum. They are located higher than that of the visible spectrum (light) because they are shorter in wavelength (higher in energy)
Sorry, but your answer is incorrect. Microwaves are much lower in frequency and have longer wavelengths than visible light:
Frequency Wavelength Quantum Energy (eV)
Microwaves 300 MHz - 300 GHz 1 meter - 1 millimeter 0.00001 - 0.001
Light ~5,000,000 GHz ~ 0.0006 millimeters 1.65 - 3.1
Therefore, there is a lot more energy in visible light: longer wavelength = lower energy
The microwaves are produced by a generator called a magnetron that is powered by electricity. The reason the microwave energy cannot 'escape' the microwave (even through the little holes in the window screen!) is because the waves cannot 'fit' through the holes in the metal screen, and the microwaves are blocked by the metal in general. The concept of them 'fitting' through the holes is a bit more complicated than just that, but that is essentially how it works.
A microwave converts electrical energy into microwave radiation, which heats food by causing water molecules in the food to vibrate rapidly, generating heat.
hahaha HELLPPP!! relative energy is a science word hahaha HELLPPP!! relative energy is a science word
The type of energy conversion for a microwave is the transformation of electrical energy into light energy. This device works by focusing microwave light on the food inside of it.
That depends how much energy they have in the first place. Like other types of radiation, they can be intense (lots of energy) or not so intense.

What energy is wasted in a microwave?
In a microwave, energy is wasted in the form of heat that escapes from the appliance and does not contribute to heating the food. Additionally, energy can be lost through inefficient conversion of electrical energy into microwave radiation, as well as losses in the components of the microwave itself.
What i the wasted energy of a microwave?
In a microwave, wasted energy can occur due to heat loss through the walls of the oven, inefficient conversion of electrical energy to microwave radiation, and energy not being absorbed by the food being heated. This can result in lower efficiency and longer cooking times.
What type of energy transformation takes place in a microwave?
In a microwave, electrical energy from the power source is converted into electromagnetic waves (microwaves) which in turn generate heat energy by causing water molecules in food to vibrate and produce heat. So, the energy transformation in a microwave involves conversion from electrical energy to electromagnetic waves and then to heat energy.
How is kinetic energy used in a microwave oven?
In a microwave oven, kinetic energy from electromagnetic radiation heats up water molecules in the food. These vibrating water molecules produce heat, which cooks the food by transferring energy throughout the molecules.
What are 2 energy conversions that takes place when you warm up a cup of cocoa in a microwave oven?
When you warm up a cup of cocoa in a microwave oven, electrical energy is converted to electromagnetic radiation (microwaves) to heat up the water molecules in the cocoa. The absorbed radiation energy is then converted to thermal energy, raising the temperature of the cocoa.

What energy transformation occurs in an oven?
The electricity (electromagnetic energy) that drives the microwave oven is routed to the magnetron, which generates the microwave energy. (The electricity and microwave energy are both forms of electromagnetic energy.) The microwaves travel through a waveguide into the cavity (the cooking space) in the oven, and used to excite chemical bonds in the food items. This is a conversion of microwave energy (electromagnetic energy) into the mechanical energy of heat.

A microwave oven converts electrical energy into what energy?
Into microwave electromagnetic radiation.
Is light energy used in a microwave oven?
Yes, light energy is used in a microwave oven to generate microwaves that heat and cook food. However, the light energy in a microwave oven is not visible to the human eye.
What energy does a microwave have?
heat energy
Does microwave radiation carry a lot of energy?
It can do certainly. In a microwave oven there is enough energy to heat food quickly
A comparison of amount of energy before a conversion with the amount of useful energy after a conversion?
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.
