Both visible light and microwave radiation are different variations of the same electromagnetic energy. Visible light has infinitesimally small wavelengths, and therefore it can pass through the screen holes. Microwave radiation has much larger wavelengths, and these wavelengths are too big to "fit" through the screen holes, and therefore the screen appears solid to the microwave radiation. The microwave radiation is therefore completely reflected by the screen.

What are microwaves created by?
a microwave is actually a particle of light below the visible spectrum that we can see. a magnetron is the device in a microwave oven that produces the microwaves by using an electromagnet that charged produces a light wave at the proper frequency to make it a microwave.
Can a microwave light a light bulb?
No, a microwave does not produce visible light that can be used to light a light bulb. Microwaves generate electromagnetic radiation in the microwave frequency range which is not visible to the human eye.
Does a microwave use light energy?
yes its does because when the microwave is on and the plate is rotating,the light is actually heating the food. It is not the visible light that does the heating, that is provided simply so you can see inside the oven. It is the microwaves that do the heating, by agitating molecules of water in the food. That's why you can't heat dry food in microwave oven. The microwaves are EM radiation like visible light, but a different wavelength.
What is the frequency range of microwaves light?
Microwave light has a frequency range of approximately 300 MHz to 300 GHz.
Is light energy used in a microwave oven?
The microwave energy in a microwave oven is of a much lower frequency than light, but light is electromagnetic energy like the microwave radiation is.

Why does the light bulb light up when the banana is in the microwave with it?
Because Microwaves always light up.
Are microwaves a form of visible light?
No, microwaves are not a form of visible light. They fall within the electromagnetic spectrum at lower frequencies than visible light. Microwaves are used in appliances like microwave ovens for cooking food.

How does the microwave expose your food to electric currents?
Microwave ovens don't expose food to electric currents, they expose food to microwaves. Microwaves are a type of electromagnetic radiation, or a type of light. The only difference between visible light and microwaves is the wavelength of the light. Wavelength is what makes blue light look different from red light (red light is made of physically longer waves). Microwaves are much shorter than visible light and have much higher energy. That energy is used to heat up the water molecules in the food you put in the microwave. That's how it heats up your food.
What color is microwaves?
my microwave is mainly white and grey with blue and orange
What is the difference in light wave and microwave?
Light waves have shorter wavelengths and higher frequencies than microwaves. Light waves are visible to the human eye and are used in various technologies such as optical communications and photography, while microwaves have longer wavelengths and are commonly used in microwave ovens, telecommunications, and radar systems.
Are microwaves are a form of visible light?
No. If you take the light bulb out of the microwave oven, then you can't tell by looking at it whether or not it's running.
Which has higher frequencies microwaves or visible lights?
Visible light has shorter wavelengths than microwaves. Microwaves, which might be considered the highest energy radio waves, have a longer wavelength (and a lower frequency) than visible light.
