Why do microwave doors have holes?
Microwave ovens are designed to keep in radiation. Against the glass, there is a protective mesh screen dotted with tiny holes. These holes are spaced appropriately so that the long microwaves are kept bouncing inside the chamber, while also allowing you to peer through and view your food, explained Jorgensen.Click to see full answer.

Also, how does a microwave door protect you?The back of the door is covered with a protective metal gauze to stop microwaves escaping. Microwave ovens are so quick and efficient because they channel heat energy directly to the molecules (tiny particles) inside food. Microwaves heat food like the sun heats your face—by radiation.Additionally, how does the wavelength of the microwaves compare with the size of the holes in the metal screen on the door of the oven? For some numerical perspective, the holes in the metal screen on the microwave oven door are about 1 mm in diameter compared to a 120 mm wavelength for the microwaves. The wavelength of the microwaves is about 120 times the size of the holes, and can’t “see” the holes to get out. In this way, what is a microwave door made of? The oven’s inside panels and doors are made of galvanized or stainless steel and are given a coating of acrylic enamel, usually light in color to offer good visibility. The cooking surface is generally made of ceramic or glass.Why can’t you stand in front of the microwave?Standing in front of your microwave may increase your exposures to microwave radiation; however, such increases are likely to be low, especially when compared to your exposures to microwave radiation from your cell phone.
