It is predicted to lie at a wavelength of 91.2 nm.
Rydberg equation is a mathematical formula that is used to predicts the wavelength of light resulting from an electron moving between energy levels of an atom. Rydbery equation is used to describe the spectral wavelengths of chemical elements. The equation is made up of different components, which include n1 and n2. The n1 of the equation has a value of 1 while the n2 runs from 2 to infinity; this makes the spectral lines to converge at point 91.2 nm.
The property to be used is sieving. you get a bowl and a sieve when you pour the sand and salt,the salt being the small particle sieve to the bowl while the sand remain on the sieve as residue

The reason why water is so recurrent is because of the general form that says: ACID + BASE → SALT + WATER
I took the liberty of balancing the equations.
Iodine (iodine-potassium iodide) staining distinguishes starch ( a polysaccharide) from monosaccharides, a disaccharides and other polysaccharides. Therefore, a bluish black color is a positive test for starch, and a yellow-ish brown color ( no color change) is a negative test for starch.
