Question

Which type of following material is used for making the front glass (wind screen) of a car?
(A) Transparent
(B) Translucent
(C) Opaque
(D) All the above

Answer 1

Hint: The front window of an aeroplane, vehicle, bus, motorcycle, truck, railway, boat, or streetcar is the windscreen, which offers sight while shielding people from the weather. Modern windshields are commonly composed of laminated safety glass, which consists of two curved sheets of glass with a plastic layer sandwiched between them for safety and glued into the window frame.

Complete answer:
Glass is a non-crystalline, typically transparent amorphous solid with broad practical, technical, and ornamental applications in window panes, dinnerware, and optics, among other things. Glass is most commonly generated by the quick cooling (quenching) of molten metal; but, certain glasses, such as volcanic glass, occur spontaneously.
Transparency in optics refers to the physical quality of enabling light to travel through a substance without significant scattering. Snell's Law may be applied to photons on a macroscopic scale. Translucency enables light to flow through, but it does not always obey Snell's law; photons can be scattered at either of the two surfaces, or internally, where the index of refraction changes. Transparent materials seem transparent, with a single colour or any combination of colours leading to a vivid spectrum of all colours. Opacity is the polar opposite of translucency.

Hence option A is correct.

Note:
When light collides with a substance, it can interact with it in a variety of ways. The wavelength of the light and the composition of the substance influence these interactions. Photons interact with objects in a variety of ways, including reflection, absorption, and transmission. Optical transparency refers to the ability of some materials, such as plate glass and pure water, to transmit most of the light that falls on them while reflecting very little. Many liquids and aqueous solutions are transparent to a large extent. Excellent optical transmission is mostly due to the absence of structural flaws (voids, fractures, etc.) and the molecular structure of most liquids.
