-- Make a slab of ice, cheese, or chocolate, 1/2 inch thick, the same shape and
slightly smaller than the bottom of your microwave oven.
-- The hardest part is: DON'T make the slab in a metal or foil pan. Either make it
in glass, or else you have to take it out of the pan when it's solid.
-- Put the slab in the microwave. If there's a turntable in the microwave, turn it off
or take it out. The slab has to remain still.
-- Start giving it 15- to 20-second shots of cooking power, until soft spots begin
to appear in the slab. When there are enough soft spots, you'll see that they're
laid out like a checkerboard, in rows and columns of spots.
-- Carefully move the slab from the oven to a piece of newspaper spread out on
the table (so you don't make a mess).
-- Measure the distance between two spots in the same row or the same column.
It's hard to tell where a soft spot begins, or where the center of it is, so you'll have
to make several measurements and try to get a good average, reliable number.
It'll be 6.12 centimeters. That's half of the wavelength of the microwave cooking
power.
-- Now look inside, under, around, on the back, top, bottom, or side of the oven.
Find a little metal plate that shows the manufacturer, model number, input power,
and cooking power. Also on that plate, it'll tell the operating frequency of the oven.
All microwave ovens operate at the same frequency. It will say either " 2.450 GHz "
or "2450 MHz ". Those are both the same number.
-- Now you have the frequency and the wavelength. Speed is their product.
(0.1224 meter) x (2,450,000,000 per second) = 299,880,000 meters per second.
The official standard speed of light in vacuum is 299,792,458 , slightly less in air.
These numbers are less than 0.03% different. That's more accurate than the speed
was known before the 1880's. Not bad for using stuff that almost everybody has
around the house these days.
The moral of the story, as far as I'm concerned, is: What a miraculous age of
technology we live in.
Emerson microwaves are manufactured in China.
Microwaves use electromagnetic radiation, specifically microwaves, to cook food.
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
Microwaves are an example of electromagnetic radiation that can be used to measure the speed of a passing car. This is commonly done using police radar guns, which emit microwaves and detect the frequency shift of the reflected waves to calculate the car's speed.
GE microwaves are manufactured in Louisville, Kentucky, USA.
No, not all over-the-range microwaves are the same size. They can vary in dimensions depending on the brand and model. It's important to measure the space where you plan to install the microwave to ensure a proper fit.
