Question

A film of oil on a puddle in a parking lot shows a variety of bright colors in swirled patches. What can you say about the thickness of the oil film?
A. It is much less than the wavelength of visible light.
B. It is on the same order of magnitude as the wavelength of visible light.
C. It is much greater than the wavelength of visible light.
D. It might have any relationship to the wavelength of visible light.

Answer 1

The frequency of an periodic wave is its spatial period, or the distance over which the wave's design rehashes. It's the distance between two contiguous relating points of a similar stage on the wave, such two neighboring peaks, box, or zero intersections, and it's an element of both voyaging and standing waves, just as other spatial wave designs.

Complete answer:
Colour is a visual insight highlight portrayed by shading classes like red, orange, yellow, green, blue, and purple. The actuation of photoreceptor cells (specifically cone cells in the natural eye and other vertebrate eyes) by electromagnetic radiation causes shading vision (in the apparent range on account of people). Shading classifications and actual shading determinations are associated with things dependent on the frequencies and forces of light reflected from them. The actual characteristics of the thing, for example, light retention and outflow spectra, impact its appearance.

A wave's frequency is controlled by the medium through which it mediums(for instance, vacuum, air, or water). Sound waves, light waves, water waves, and intermittent electrical driving forces in a channel are generally instances of waves. A sound wave is an adjustment of pneumatic force, though the power of the electric and attractive fields changes in light and other electromagnetic radiation.

Varieties in the tallness of a waterway are known as water waves. Nuclear areas change in a gem cross section vibration.No colour would happen if the thickness of the oil covering was not exactly a large portion of the frequencies of noticeable light. On the off chance that the oil film was fundamentally thicker, the tones would drain together and get white or dim.

Hence option B is correct.

Note: Colour science is frequently known as chromatics, colorimetry, or simply shading science. It includes investigation into how the natural eye and mind see tone, the beginning of shading in materials, shading hypothesis in craftsmanship, and the physical science of noticeable electromagnetic radiation (that is, the thing that is generally alluded to just as light).
