In which year did Albert Einstein predict a new state of matter, the Bose-Einstein condensate (BEC), based on a quantum formulation by the Indian physicist Satyendra Nath Bose?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1924.
Albert Einstein predicted the Bose-Einstein Condensate (BEC) in 1924, based on a quantum formulation by Indian physicist Satyendra Nath Bose. Bose sent his paper on the statistical behavior of photons to Einstein, who recognized its significance and extended the concept to atoms, leading to the prediction of BEC. This state of matter occurs at extremely low temperatures, where a group of atoms occupies the same quantum state, behaving as a single quantum entity. BEC was experimentally realized in 1995.
