In the context of modern scientific research, consider the following statements about 'IceCube', a particle detector located at South Pole, which was recently in the news :
1. It is the world's largest neutrino detector, encompassing a cubic kilometre of ice.
2. It is a powerful telescope to search for dark matter.
3. It is buried deep in the ice. Which of the statements given above is/are correct ?
-
A.
1 only
-
B.
2 and 3 only
-
C.
1 and 3 only
-
D.
1, 2 and 3
Correct Answer:
D. 1, 2 and 3
Explanation:
All three statements about IceCube are correct:
IceCube is the world's largest neutrino detector, encompassing a cubic kilometer of Antarctic ice with 5,160 digital optical modules buried deep between 1,450 meters to 2,450 meters beneath the surface.
It is a powerful telescope used to search for dark matter and study high-energy astrophysical neutrinos, cosmic rays, and neutrino oscillations, contributing to understanding dark matter and other particle physics phenomena.
IceCube is buried deep in the ice at the South Pole, making use of the natural ice as a detection medium for Cherenkov radiation caused by neutrino interactions.
Therefore, the correct answer is (d) 1, 2 and 3
