A teacher of Xth class, during teaching explains the importance of the music in our daily life. She was telling to her students that in the Indian system of music, there are seven musical notes in a scale sa, re, ga, ma, pa, da, ni. And in the west notations used are do, re, mi, fa, so, la, ti. The notes in a scale are separated by whole frequency intervals of tones. Every eighth note is similar to the first one and it is first note of next scale. A musician use these notes for composing music of a song.
Read the above passage carefully and answer the following questions accordingly.
(i) Is the situation discussed above is similar to something in chemistry? Explain.
(ii) What are the limitations of the above principle in case of chemistry?
(iii) What are the values you will infer from above passage?
(i) The situation discussed above is similar to the “Newlands’s law of octaves”. Newland arranged the known elements in increasing order of atomic mass. He found that the every eighth element had properties similar to that of first one. He compared it to the octaves found in music.
(ii) The limitations of “Newland’s law of octaves” are as follows:
● This law was only applicable till calcium. After calcium, every eighth element didn’t possess properties similar to first one.
● Newland assumed that no more elements would be discovered in future but new elements were discovered later on which couldn’t fit in this law.
● Newland put two dissimilar elements in the same slot.
(iii) The value we can infer from above passage is that music is important in our lives.
