8 Compute reflected, refracted, and transmitted rays

With a refractometer the refractive index of optical media is determined. If the refractive index of a chemical is known it can be used after a synthesis to determine the sample's purity or to audit the synthesis' success.

And in this impossibly beautiful picture, you see the main rings backlit by the Sun, you see the refracted image of the Sun and you see this ring created, in fact, by the exhalations of Enceladus.

I mean, this is a glimpse of the interior of our Hong Kong bank of 1979, which opened in 1985, with the ability to be able to reflect sunlight deep into the heart of this space here.

Japan Aerospace Exploration Agency flew a solar sail, and you can see here that the sail expands out, and you can still see the fold lines.

And I'm following all the light kicks on this thing and making sure that as I'm holding the light in the same position, I'm getting the same type of reflection on it that's the level of detail I'm going into this thing.

Tremendous fire.

Now even light will be bent by those paths.

And then, when you shine sunlight at them, the sunlight will be reflected back, just as it is in the eyes of an animal.

I'm sure most of you know from school physics that it's basically splitting a white light into colors.

And the phosphor is excited by the blue and makes the light white and warm and pleasant.

So for direct light, it takes only one bounce, for off axis light it might take two, and for extreme off axis, it might take three.

Light came out of it in every direction.

They were throwing those lights around.

Also, the atmosphere has a brightness all of its own, owing in part to scattering of electromagnetic radiation from various sources (such as city lighting, Moon light, auroral type phenomena and lightning).

Find the energy of X ray spectral lines

Optical debris can be detected by reflected sunlight when the debris object is sunlit while the ground below is dark.

That's not luminescence, that's reflected light from the gonads.

It makes a shambles of the light.

Analyse X ray Fluorescence data

Flames dazzle and flash and lash at the rocks.

XMM (X ray Multi Mirror) for X ray spectroscopy of cosmic objects

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

Bright have already shot the city head of ancient Rome

Using a unique technique for concentrating the solar light, splitting the spectrum to various spectral bands, and using each band for direct optical pumping of different lasers near their emission band resulted in an overall efficiency of 20 per cent.

From the wicked, their light is withheld. The high arm is broken.

From the wicked, their light is withheld. The high arm is broken.

And from the wicked their light is withholden, and the high arm shall be broken.

And from the wicked their light is withholden, and the high arm shall be broken.

He would shoot his light saber across the abyss, making a blade of light, and then scamper across on this blade of light.

The x ray absorption spectroscopist's periodic table

And by night, artificial light in each one emanates and comes out to the outside.

This side of the street don't get the afternoon sun.

The only thing left now is a permanent shadow of positive light.

The little dust particle will again, reflect the light, and we realize the existence of light.

The sun and moon stood still in the sky, at the light of your arrows as they went, at the shining of your glittering spear.
