what is the difference between the regular or specular reflection from diffuse reflection?
604936
There are two types of reflection: specular and diffuse. Specular reflection * occurs on smooth surfaces. Diffuse reflection * occurs on rough surfaces. The rougher the surface, the more diffuse the reflection.

Reflection means that they are thrown back from a surface; absorption means that they are incorporated by a surface and transformed into heat energy. Different surfaces reflect and absorb differently. The ratio between absorption and reflection is called albedo.

A sample is placed in the light path, and the instrument compares the intensity of the light going through the sample (I) to the intensity observed without the sample (Io). The Absorbance is seen to be proportional to the number of sheets of the colored material.

['the light must be travelling from a more dense medium into a less dense medium (ie glass to air)', 'the angle of incidence must be greater than the critical angle.']

The angle of reflection is equal to the angle of incidence. Both angles are measured from the normal. The normal is an imaginary line at right angles to the plane mirror.

Tinted glass - (heat absorbing glass) is made by adding color pigments to the raw materials in the float process. ... Reflective glass - (solar control glass) is a clear or tinted glass that has a thin layer of metal oxide, approximately . 000003" thick, applied to the surface of the glass.

Seeing the Difference As you can see, there is a slight difference in color but the most noticeable difference is how they reflect back. The polished is a fuzzy, vague reflection versus the chrome which is a crisp mirror-like reflection.

When passing through a transparent specimen, the illuminating light wavefront is not modified in a brightfield microscope, nor is the image-forming wave absorbed by the specimen. If the specimen is somewhat out of focus, a thin grayscale shadow produced by refracted light is observed through the eyepieces.

Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth, flat mirror in Figure 2.

There is a big difference. Reflective tape acts as a mirror, so it sends the light back out in different directions. Retro-reflective material is made with tens of thousands of tiny glass beads that reflect light and send a focused image directly back to the original light source. ... These designs light you up at night!

A material defines the optical properties of an object: its color and whether it is dull or shiny. A texture is a pattern that breaks up the uniform appearance of the material. Very few objects in the real world have completely uniform surfaces.

The main difference is composite reflectivity shows the highest dBZ (strongest reflected energy) at all elevation scans, not just the reflected energy at a single elevation scan. ... Base reflectivity only shows reflected energy at a single elevation scan of the radar.

regular reflection : it is when parallel rays of light fall on a smooth surface and reflect parellely. irregular reflection : it is when parallel rays of light fall on a rough surface and reflect in different directions.

Simply put, the difference between these two options is that the front projection reflects light off of the screen while rear projection diffuses the projector's light through the screen.

The main difference: "Highlighter is for a concentrated area of light, while an illuminator casts light more generally," explains Anthony.

In general terms anti-glare coatings use either diffuse particles or etching on the substrate's surface, while anti-reflective coatings utilize film structure over the substrate surface. ... There are however instances where both solutions can be used in conjunction for maximum reflection/glare reduction.

This light does not directly enter the objective lens. In contrast, a solid cone of light illuminates and enters the objective lens in brightfield. Only light that is scattered by the sample (depicted by the lines in the diagram) and enters the objective lens is seen as an image in darkfield.
