So the wavelength, in this situation you would say the velocity your velocity is equal to your wavelength times your frequency.

What's the wavelength here?

What is the light's wavelength?

That's also the wavelength.

That is also one wavelength.

That would be my wavelength.

And we call that a wavelength.

So distance is not one wavelength.

So this is also one wavelength.

The notation for wavelength tends to be the

So it's 5 meters.

Hue

Hue

That is also going to be the wavelength.

So I could rewrite this as wavelength.

The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye.

So it's wavelength divided by period.

So velocity is equal to wavelength times your frequency.

You are now smaller than the wave length of visible light

I'm a spectroscopist.

And then in this spectrum

Which is the same thing as wavelength times 1 over my period.

So this is equal to 5 meters per cycle, which would be your wavelength in this situation.

It doesn't emit in the electromagnetic spectrum. It doesn't reflect.

And we are simply running out of spectrum.

Here you are, balloons. All colors of the rainbow.

A simple thermal source is sunlight, the radiation emitted by the chromosphere of the Sun at around 6,000 Kelvin peaks in the visible region of the electromagnetic spectrum when plotted in wavelength units and roughly 44 of sunlight energy that reaches the ground is visible.

P680 can also directly absorb a photon at a suitable wavelength.

And there's a lot of different ways you can define a wavelength.

To go one wavelength, we have to go back to the same position.

let me write it this way wavelength is equal to how far the wave has traveled after one period.

Well, the distance you travel in a period is your wavelength after one up, down, back again.

So we could say velocity is equal to wavelength over period.

This was the first indication of the existence of the entire electromagnetic spectrum.

And light is part of the electromagnetic spectrum.

It's nice to have a champion, thank you.

because my job is spectroscopy.

And all you need is time and money to make your spectrograph.

Now the theme of this year's TED Conference is Full Spectrum.

Not only that, I compared it to the entire spectrum.

NASA's really cool.

You know, I feel sorry for that nice Mr. Vole.

The shorter wavelength allows it to read discs containing much more information.

They're smaller than a wavelength of light, so we have no way to directly observe them.

But if you look at the spectrum, birds and us, we see red, green and blue and see that spectrum.
