Marie and Pierre noticed burns on their fingers after handling test tubes containing radioactive substances. This observation led to
A. the discovery of natural fluorescence.
B. the discovery of X-rays.
C. the discovery of radiation therapy.
D. the discovery of uranium.
Is the answer B? Thanks in advance
I would choose C
Line JK bisects line LM at point J. Find JM if LJ=23 cm
Yes, the correct answer is B. The observation of burns on their fingers after handling test tubes containing radioactive substances led to the discovery of X-rays. To arrive at this answer, we can eliminate the other options and explain why B is the correct choice:
A. The discovery of natural fluorescence: Natural fluorescence relates to the emission of light by an object or substance after absorbing electromagnetic radiation, but it does not explain the burns on Marie and Pierre's fingers. This option can be eliminated.
C. The discovery of radiation therapy: Radiation therapy involves the use of ionizing radiation to treat cancer, but it does not explain the burns on their fingers. This option can also be eliminated.
D. The discovery of uranium: Although uranium is a radioactive element, it does not specifically explain the burns on Marie and Pierre's fingers. This option is also incorrect.
By process of elimination, we can conclude that the correct answer is B, the discovery of X-rays.
