Explain the Law of Octaves given by Newland.
(N/A) John Alexander Newland in $1865$ proposed the Law of Octaves.
- Law: "Every eighth element has properties similar to the first element."
- The relationship is analogous to the musical scale where every eighth note resembles the first. For his work,he was later awarded the Davy Medal in $1887$ by the Royal Society,London.
