1. wavelengths

In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The inverse of the wavelength is called the spatial frequency. Wavelength is commonly designated by the Greek letter lambda (λ). The term wavelength is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids.Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.Wavelength depends on the medium (for example, vacuum, air, or water) that a wave travels through. Examples of waves are sound waves, light, water waves and periodic electrical signals in a conductor. A sound wave is a variation in air pressure, while in light and other electromagnetic radiation the strength of the electric and the magnetic field vary. Water waves are variations in the height of a body of water. In a crystal lattice vibration, atomic positions vary. The range of wavelengths or frequencies for wave phenomena is called a spectrum. The name originated with the visible light spectrum but now can be applied to the entire electromagnetic spectrum as well as to a sound spectrum or vibration spectrum.

### Examples of wavelengths in a Sentence

1. I think we chose the Tarantula Nebula as one of our first targets because we knew it would demonstrate the breadth of Spitzers capabilities, that region has a lot of interesting dust structures and a lot of star formation happening, and those are both areas where infrared observatories can see a lot of things that you cant see in other wavelengths.

2. The longer wavelengths enable Webb to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies, as well as to look inside dust clouds where stars and planetary systems are forming today.

3. For decades radio interferometry has been done at centimetre wavelengths using telescopes spread across continents, however, if you do the same observations at millimetre wavelengths then you canproduce images with better resolution, and see (in silhouette) the black hole at the centre of our galaxy.

4. If Dr Homer take that pigment away, then the light can enter the stroma -- the little fibers that look like bicycle spokes in a light eye - and when the light scatters it only reflects back the shortest wavelengths and that's the blue end of the spectrum.

5. Now we know these very different observatories operating at very different wavelengths can see the same fast, energetic impulse.
