for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
100,000 mm is 100m which is just a bit longer than a football field
a football field is 260 feet long. No, a football field is 360 feet long including the end zones.
Ultraviolet light, x-rays, and gamma rays are all electromagnetic waves that are more energetic than visible light.
A city block might be 100 feet long, but it would be small for a block. They can be 200 feet long, or much longer. A US football field is 300 feet long between the goal lines, slightly longer overall. The distance 100 feet is twice the width (50 ft) of the smallest residential lots in many suburban areas.
An arena football field is 50 yards long.
American Football Field: Let's see, there are: One million micrometers in a meter. 100 yards in an American football field. 91.44 meters in 100 yards. So, an American football field would be 91440000 micrometers long. Did you really mean micrometers? Just to add to the previous (accurate) post.... Canadian Football Field A Canadian Football field is 100 metres long so 100,000,000 micrometers long. Football/Soccer Field If you are talking about Football as in what North American's call Soccer, then the field is anywhere from 90 to 120 metres long (according to FIFA). Thus it is anywhere from 90,000,000 to 120,000,000 micrometers long.
A Professional Field is 120 Yards long
In American football, it is 100 yards long.
long houses co be 20 to 30 ft long they can be even longer

For electromagnetic waves: thermal radiation and radio waves are pretty long. For sound waves: bass sound waves are pretty long, so is quiet. For water waves: the tides
