The Invisible Man, by Wells

- I found a general principle of pigments and refraction—a formula, a geometrical expression involving four dimensions.†
Chpt 19 *
- Either a body absorbs light, or it reflects or refracts it, or does all these things.†
Chpt 19
- If it neither reflects nor refracts nor absorbs light, it cannot of itself be visible.†
Chpt 19
- A diamond box would neither absorb much of the light nor reflect much from the general surface, but just here and there where the surfaces were favourable the light would be reflected and refracted, so that you would get a brilliant appearance of flashing reflections and translucencies—a sort of skeleton of light.†
Chpt 19
- A glass box would not be so brilliant, not so clearly visible, as a diamond box, because there would be less refraction and reflection.†
Chpt 19
- A box of very thin common glass would be hard to see in a bad light, because it would absorb hardly any light and refract and reflect very little.†
Chpt 19
- And if you put a sheet of common white glass in water, still more if you put it in some denser liquid than water, it would vanish almost altogether, because light passing from water to glass is only slightly refracted or reflected or indeed affected in any way.†
Chpt 19
- This is because the powdering multiplies the surfaces of the glass at which refraction and reflection occur.†
Chpt 19
- In the sheet of glass there are only two surfaces; in the powder the light is reflected or refracted by each grain it passes through, and very little gets right through the powder.†
Chpt 19
- The powdered glass and water have much the same refractive index; that is, the light undergoes very little refraction or reflection in passing from one to the other.†
Chpt 19
- And if you will consider only a second, you will see also that the powder of glass might be made to vanish in air, if its refractive index could be made the same as that of air; for then there would be no refraction or reflection as the light passed from glass to air.†
Chpt 19
- Oil white paper, fill up the interstices between the particles with oil so that there is no longer refraction or reflection except at the surfaces, and it becomes as transparent as glass.†

Definitions:
-
(1)
(refract) to change the velocity of a beam of light or other wave-form as it passes from one medium into another (apparently bending it when passing at an angle)
- (2) (meaning too rare to warrant focus)
