A cosmic radiation Correct Answer Incorrect Answer
B quantum statistics Correct Answer Incorrect Answer
C expanding universe Correct Answer Incorrect Answer
D theory of super conductivity Correct Answer Incorrect Answer

Solution

Cosmic Radiation:- • These are high-energy particles that travel through space and bombard Earth's atmosphere. • They were discovered by Victor Franz Hess in 1912, when he made a series of balloon ascents to measure the ionization of the atmosphere at different altitudes. (Hence option 1 is correct). • He found that the ionization increased with altitude, even though the atmosphere becomes less dense at higher altitudes. • This led him to conclude that there must be a source of radiation coming from outside the atmosphere.
