And we imaged the manuscript in 14 different wavebands of light.

Atoms, can't see them. Nobody ever will.

That's really, really, really short.

These are normal cells.

Violet light has a shorter wavelength than red light.

How can you have a picture of an atom?

Wavelength

And by tiny, I mean really.

When you think about it, this is pretty weird.

Iridiscence wave length

In time, my dear.

Different wavelengths of light have different activities of doing that.

Do you have to give in order to specify any radiance value you want to gather?

And then I put some ultraviolet filters on my camera and took a very, very long exposure with the particular frequencies of ultraviolet light and this is what I got.

And we'll say the frequency is 1.76 kilohertz, or 1760.

Now a laser is different.

The OED defines spectrum as The entire range of wavelengths of electromagnetic radiation, from the longest radio waves to the shortest gamma rays of which the range of visible light is only a small part.

When the frequency goes up, the wavelength comes down.

Light and sound travel in waves.

And so one of the tools that we can use to sample the oceans is acoustics, or sound waves.

You might have heard that light is a kind of wave and that the color of an object is related to the frequency of light waves it reflects.

Select here the value which represents the width of the local neighborhood.

Select here the value which represents the height of the local neighborhood.

Select here the value which represents the standard deviation of the Gaussian, in pixels.

Select here the value which represents the extent of the implosion.

Select here the value which represents the elevation of the light source direction. The elevation is measured in pixels above the Z axis.

Select here the value which represents the percent threshold of the solarize intensity.

Select here the value which represents the wave length of the sine wave.

(Laughter)

A good looking girl always gets your interest, doesn't she?

Wavelength interference, weak frequencies, spotty, irregular.

like we can with the cork and the ocean.

And guess what?

So enough about bobbing corks... what about light and color?

Multiwavelength Catalogs

Well, I wasn't talking to you. ( chuckles )

So, in this yellow looking region, two different kinds of light waves are present one with a red frequency, and one with a green frequency.

What they didn't tell you in physics in eighth grade physics but they should have, and I wish they had, was that if you multiply the frequency times the wavelength of sound or light, you get a constant.

White waves of the Yangtze so long

Covered with plastic fragments.

The power spectrum of this density field and characterizes the distribution of one of different size.

And all of you know the wave equation is the frequency times the wavelength of any wave ... is a constant.

This sets the rightmost wavelength of the spectrum.

This sets the leftmost wavelength of the spectrum.
