In which of the following transitions will the wavelength of light emitted be minimum?
- A n = 5 to n = 4
- B n = 4 to n = 3
- C n = 3 to n = 2
- D n = 2 to n = 1
Answer & Solution
Correct Answer
(D) n = 2 to n = 1
Step-by-step Solution
Detailed explanation
n = 5 to n = 4: \(\left(\frac{1}{4^2} - \frac{1}{5^2}\right) = \left(\frac{1}{16} - \frac{1}{25}\right) = \frac{9}{400}\) n = 4 to n = 3: \(\left(\frac{1}{3^2} - \frac{1}{4^2}\right) = \left(\frac{1}{9} - \frac{1}{16}\right) = \frac{7}{144}\) n = 3 to n = 2:…

Proteins are the polymers of about twenty different a-amino acids which are linked by peptide bonds. Proteins perform various structural and dynamic functions in the organisms. Proteins which contain only a-amino acids are called simple proteins. The secondary or tertiary structure of proteins get disturbed on change of pH or temperature and they are not able to perform their functions. This is called denaturation of proteins. Enzymes are biocatalysts which speed up the reactions in biosystems. Vitamins are accessory food factors required in the diet. They are classified as fat soluble (A, D, E and K) and water soluble (B group and C). Deficiency of vitamins leads to many diseases. Nucleic acids are the polymers of nucleotides which in turn consist of a base, a pentose sugar and phosphate moiety. Nucleic acids are responsible for the transfer of characters from parents to offsprings. There are two types of nucleic acids DNA and RNA. DNA contains a five carbon sugar molecule called 2-deoxyribose whereas RNA contains ribose.
