One way, is to turn on your light switch and observe how long it takes for the light to reach to the other side of the room. (How long it takes for the room to go from dark to light.) Be careful not to blink or you'll miss it.

∙ 10y ago-- Put a smooth slab of chocolate or ice flat in the microwave oven.
-- Zap it for 10 or 15 seconds at a time and check it, until you begin to see
spots where it's starting to melt.
-- The spots will be arranged in columns and rows. Measure the distance
between spots in one column or in one row. The distance will be roughly
6.1 centimeters. Write it down.
-- Look on the information plate inside the oven or on the back. It will tell the
frequency of the energy it uses to cook. The frequency will be 2.45 GHz.
-- The speed of the wave is (wavelength in meters) x (frequency in hertz).
-- The distance between the spots is 1/2 wavelength.
The wavelength is 12.2 centimeters = 0.122 meter.
-- 2.45 GHz is 2,450,000,000 Hz
-- The wave speed is (0.122) x (2,450,000,000) = 298,900,000 meters per second.
That number, which you calculated using only a ruler and some ice,
is only about 0.27% lower than the actual speed of light in air.
Oh ! Did I forget to mention that the speed of microwaves is the same as
the speed of light ? Sorry.

What is the use crystal diode in microwave test bench?
to produce freq in the range of ghz tat is microwave freq range
Can microwave transmission use terrestrial systems?
it is the transmission of microwaves. One person throws a microwave to another person and so on.
What is the wavelength for 835.6 MHz?
You didn't specify what kind of wave. Use the relationship: speed = frequency x wavelength.You didn't specify what kind of wave.

What brand of microwave was the first to use a turntable?
According to a document from the Sharp Corporation (refer to the link below; n.b., it is a huge PDF document!): "1966 R-600 Turntable Microwave Oven Sharp developed the world's first microwave oven to use a turntable, introducing it as Japan's first consumer model."
What uses microwave radar?
No. Radar use electromagnetic radiation of a much longer wavelength
Is there a light inside of the microwave when it is not in use?
No, when it is not in use, the microwave would not have a light on. Why would you want the light on when you are not using it and waste energy?
How can you measure the speed of light accurately?
A way to measure the speed of light pretty accurately is by conducting an experiment in which you use chocolate and a microwave. To find out more about this experiment you can go on everything2.com. its quite interesting. In fact im thinking of making this my science fair project!!!
What is use of microwave?
Communications. Heating. Speed detection. Currently the limit where we can cloak objects... we can hide them so they cannot be "seen" using a microwave light source.
How do you use light speed in a sentence?
A asteroid travels at the speed of light.
Is the interior light a necessity for a Panasonic microwave because your light is not on when your microwave is in use?
The purpose of the light in a microwave oven is to enable the user to observe the progress of the cooking, and to serve as another indication ... in addition to the sound of the fan ... of when the oven is energized. The light is only a convenience, and has no effect on the operation of the appliance.
Which formula you use to calculate for the speed of light in water?
Speed of light in water = speed of light in vacuum/refractive index of water
Why use constants?
Constant is the speed of light and as the speed of light cannot change it is 'constant'
How does a microwave use light energy?
Only as a light bulb to illuminate the chamber and in the control display to tell what it is doing.
Is it safe to use a microwave oven without the light?
Yes. It is also easy to replace the light - look in your manual
How does a ship use light speed?
Nothing except electromagnetic radiation uses light speed.
What part of the electromagnetic spectrum is used in ovens?
In a microwave oven, we find that microwave energy (from the microwave portion of the electromagnetic spectrum) are used. In a conventional oven, gas or electricity is used to create infrared heat, so we find infrared radiation (from the infrared portion of the electromagnetic spectrum, which is just below the visible light or optical portion) used there. If the oven happens to be a combination microwave and conventional, we'll find both types of electromagnetic waves generated for use inside.
Is it safe to use a microwave without a light bulb cover?
There is a small chance that if you splatter something it will get in the light bulb terminal and make it rust or cause the light to shut off or burn out. It isn't going to hurt the microwave if you don't have the cover on though.
