How does a microwave use waves?
A Microwave uses electomagnetic wavelengths, which can be as long as one meter.
How do microwave ovens allow light to escape but not microwaves?
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 can you infer from a wave with short wavelength?
Low amplitude
Which electromagnetic wave has wavelengths ranging from the size of a printed period to the length of a pen?
gg
What are infra red rays?
== == Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.

How does a microwave relate to science?
A microwave heats things up by blasting wavelengths at whatever is inside them, microwaves to be exact, which is how they got their name.
Why is it impossible for us humans to see microwave radio waves an x-ray wavelengths?
Because the cells in the retina of the eye do not contain pigments that absorb these wavelengths.
What is a microwave radiation?
Radio with mm to cm range wavelengths. It is longer wavelength than IR.
Why use microwave for satellites?
The microwave has high enough frequency to carry the information and long enough wavelengths to penetrate the atmosphere. They are also easy to produce and easy to detect.
What can you infer from a wave with short wavelength?
Low amplitude
What are the use of microwave signals?
Microwave frequencies are generally considered to be in the region above 1000 Megahertz, (About 30 cm wavelength.) and as the gain of an antenna depends on it's size in wavelengths, it is possible to make very tightly focused beams at these wavelengths. This then allows low power transmitters to communicate over long distances by aiming a beam of energy at a receiving antenna. The disadvantage is that it is strictly line of sight, so mountains or earth's curvature will block the signal, hence microwave systems are often mounted on towers or tall buildings.
What wavelengths are used for radio frequency?
In round figures 1 Km (AM broadcast radio) to 0.1 mm (microwave).
What type of wavelength are commonly used to communicate with satellites?
Communication is usually done with wavelengths in the microwave part of the spectrum.
Are we humans not able to see light from sun clear because of its brightness or the wavelengths?
We have NO TROUBLE at all seeing visible light wavelengths from the sun.We cannot see the radio, microwave, infrared, ultraviolet, or x-ray "light" from the sun because our eyes are not sensitive to these wavelengths.
