Miscellaneous Others

With reference to 'Bose-Einstein Condensate', often termed as the fifth state of matter, which of the following statements is/are correct?

1. Its existence was posited by Albert Einstein and Indian physicist Jagadish Chandra Bose.

2. It is formed when atoms of certain elements are heated to near critical temperature.

3. It can be used in creation of atomic lasers and atomic clocks.

Select the correct answer using the code given below.

1 and 2 only

3 only

2 and 3 only

1, 2 and 3

Explanation:

• A Bose-Einstein condensate (BECs) is so named because its existence was posited almost a century ago by Albert Einstein and Indian mathematician Satyendra Nath Bose. It is often termed as fifth state of matter. Hence, statement 1 is not correct. • It exists when atoms of certain elements are cooled to temperatures near absolute zero. At that point, clusters of atoms begin functioning as a single quantum object with both wave and particle properties. Hence, statement 2 is not correct. • BECs have also been used to create atom lasers, atomic clocks and gravitational, rotational or magnetic sensors with excellent sensitivity. Hence, statement 3 is correct.
