    The famous physicist Victor Franz Hess is known for the

    discovery of:
    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.
