2 molecules of amino acids joined to form a peptide bond and the resulting molecule would be dipeptide.
Explanation:
When two amino acid molecules combine they form peptide bonds and in the process release one water molecule and a dipeptide is formed. This process is called dehydration synthesis. Many amino acid molecules eventually connect by peptide bonds resulting in a protein molecule.
Light speed in water is 2.25 times 10^5 m/s so the index of refraction is higher than the index of refraction of light in a vacuum which is 1.0. (speed in vacuum for light is 300,000 km/s)
Index of refraction of light in water is 3.0 time 10^5 m/s divided by 2.25 times 10^5 m/s = 1.33.
