resonators that scatter blue light Answer: A bit of background: The white light from the sun is a mixture of all colours of the spectrum. Each colour of light ahas a wavelengths. The visible part of the spectrum ranges from red light (wavelength =720 nm), to violet (wavelength =380 nm), with orange, yellow, green, blue and indigo between. The human eye reacts most strongly to strongly to red, green and blue wavelengths. This gives us colour vision. The explanation: Light passing through a clear fluid with suspended particles is scattered. Some wavelengths like blue are scattered more strongly. The first person to notice this and experiment with it was John Tyndall in 1859. So he got to mane the effect the Tyndall Effect. He made three important observations: * From the side, (the way we see most of the sunlight in the sky) the beam can be seen by the blue light it scatters * The light seen directly at the end (looking towards the source) is red. This is the way we see the sunlight at sunset
* The scattered light is polarized. This is why polarized sun glasses make some parts of the sky seem darker.
Some early researchers (Tyndall and Rayleigh) thought that the blue colour of the sky must be due to small particles of dust and droplets of water vapour in the sky. Later scientist discounted this and proposed that oxygen and nitrogen molecules are the cause of the scattering.
In 1911 Einstein did the math to prove that the molecules could cause the scattering. Technically the molecules scatter light because the electromagnetic field of the light waves induces electric dipole moments in the O2 and N2 molecules.
because it is a non polar molecule and only van der Waals forces act between the molecules

because the magnet causes particles called electrons in the atoms of the nail to align along the magnet's lines of force. The atoms with aligned electrons then act like tiny bar magnets themselves.
predominantly large particles"As a particle gets bigger, it is no longer selective in the wavelength it scatters. You can see this change if you carefully watch someone smoke. The smoke off the end of the cigarette is made up of particles that are very small compared to the wavelength of visible light, and thus appear blue, particularly if viewed against a dark background. When you inhale the smoke into your lungs, exposing yourself to great health hazards, some of the smoke stays suspended in your lungs until you exhale. Your lungs are warm and moist, and the moisture begins to condense on the smoke particles forming a type of polluted smog in your lungs (yuck!). When you exhale, the particles have become larger due to the condensation occurring in your lungs, large enough so that the smoke particles scatter light independent of wavelength, and the exhaled smoke looks white."
The electron-pair geometry of CS2 is linear because the Lewis structure is S=C=S. Double bonds act as one electron pair to help determine electron-pair geometries of molecules according to VESPR theory
The strongest intermolecular forces exist between polar molecules, because the polar molecules act as tiny dipoles.
molecules ct different because they are formed withdifferent atoms
because its connected to the oxygen
Because they act like a normal factoy would.;}:]
A coloured substance can only act as a dye if its molecules can stick to the molecules of the material. This is called mordancy, and depends on the chemical groups present on the molecules of the coloured substance and on the molecules of the material. Think of it as a lock and a key, the key has to be the right shape to fit into the lock.
Because we know that all molecules that act as antigens produce an antibody so they have a property of antigenicity but not all give the immune response.
Ozone molecules act like a blanket. They are the ones who protect us. The protection is against the UV rays.
A single enzyme molecule can act on about 1000 substrate molecules per second.
simply because DNA molecules cannot fit outside of the nucleus therefore Rna is needed
Enzymes act as catalysts in living things.
enzymes are protein molecules that act as biological catalysts
Complex molecules are broken down into simple molecules by the action of specialised proteins called enzymes. The three digestive enzymes are:amylases, which act on the carbohydratesproteases, which act on the proteinslipases, which act on the lipids
