Wavelength is the distance between two points of the same phase in consecutive cycles on a periodic wave. Wavelength can be expressed in many units of distance, the most logical being the meter. However, because so many kinds of electromagnetic...

The linear distance between successive identical points (usually taken as the peak or trough) on a wave of energy as it is transmitted past the reference point. The wavelength has a direct relationship with the FREQUENCY and with the velocity of...

The distance, measured along the line of propagation, between two points that are in phase on adjacent waves. A property of radiant energy, such as IR, visible, or...

n. The distance, measured in the direction of propagation, between two points in the same phase in consecutive cycles of a wave. Symbol:...

In physics, wavelength is the distance between repeating units of a propagating wave of a given frequency. It is commonly designated by the Greek letter lambda (λ). Examples of wave-like phenomena are light, water waves, and sound...

Having coaxed all the life they can out of an 8-year-old ultraviolet light-detecting space telescope, scientists will reluctantly turn it off later this month.After that, NASA's Fuse observatory will be "just another piece of space junk," orbiting the earth every 100 minutes until it falls...

It seems hardly an hour of prime-time TV viewing goes by without some ad pitching a miracle cure for wrinkles.As baby boomers age, more people are searching for the fountain of youth. All types of companies -- from drug and cosmetics firms to makers of...

The ultrahigh-speed Internet2 network just got 10 times faster, partly in anticipation of rising demand for capacity after the world's largest particle collider opens near Geneva next year.Until recently, the Internet2 had a theoretical limit of 10 gigabits per second, which is thousands of times...
