8 Compute reflected, refracted, and transmitted rays

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.

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

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

It makes a shambles of the light.

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

We see light reflected off the Moon.

2, 3 Show specified diffuse and ambient light

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

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.

The optical, multispectral scanners sensed the solar energy reflected or emitted by surface features.

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

This bit, the big secret of automotive design reflection management.

Why? Because if the tile in that shadow were in fact in shadow, and reflecting the same amount of light to your eye as the one outside the shadow, it would have to be more reflective just the laws of physics.

The laser retroreflector is a passive optical device used as a target by ground based laser ranging stations in order to determine the accurate position of the satellite.1

It's not about the shapes, it's how the shapes reflect light.

(c) Albedo a measure of the reflectivity of an object which characterizes the optical visibility of an object

(d) Albedo a measure of the reflectivity of an object that characterizes the optical visibility of an object

If they are under the same light, reflecting the same amount of light to your eye, then they must be equally reflective.

Its surface is covered by 426 reflectors to return the laser light back to the observatory.

Now, what we're doing is, we're doing one that will be both frontlit and backlit.

And this is very important light to capture, because this is the light that reflects off the first surface of the skin.

The first is the optical sensor, which reacts to the behaviour of light passing through the test solution, recording such phenomena as the absorption or fluorescence of light, light scattering or spectrophotometry.

It's this non tracking collector with these six tuba like horns, and each of them collect light in the following way if the sunlight strikes right here, it might bounce right to the center, the hot spot, directly, but if the sun is off axis and comes from the side, it might hit two places and take two bounces.

An advantage of optical measurements over radar measurements is that the signal intensity from reflected sunlight falls off only as the square of the distance or altitude, whereas the radar signal return falls off as the fourth power of distance.

The mirror was still being ground and polished, resting on an 18 point support just as in the future telescope cell.

(c) Photo neutron interrogation photo induced neutron emission occurs when the energy of an incoming photon (X ray or gamma ray) is above a certain threshold and atoms of low atomic weight undergo photonuclear reactions that emit neutrons.

Now, let's see the surfaces according to the quality of light that they reflect.

There is a single candle flickering in the center by an arrangement of reflective glasses, it reflects into infinity in all directions.

Your efficiency goes down with more bounces, because you lose about 10 percent with each bounce, but this allowed us to collect light from a plus or minus 25 degree angle.

In order to achieve a high quality optical surface in all applicable positions of the telescope, a new support, or mirror cell, for the primary mirror will be necessary.

Tremendous fire.

(c) Polarization and directionality of the Earth apos s reflectances instrument (POLDER) by CNES

The Goto 45 centimetre reflecting telescope, for example, is equipped with a photometer, a spectrograph and a photographic camera.

And he kind of flicked it open in a way that caught the sun that was just coming over the Rockies, it was very it was, it was impressive.

For passive optical measurements, the signal intensity return is inversely proportional to the square of the distance or altitude of the object since the incident illumination from the Sun is essentially independent of altitude.

We studied the acoustics with laser stuff, and they bounce them off this and see where it all works.

But when it's backlit, it's color and when it's frontlit, it's black and white at three times the resolution.

Light came out of it in every direction.

They were throwing those lights around.

CNES will provide the altimeter and the Doris system, while NASA will supply the radiometer, the laser reflector and the positioning system.
