Questions about Physics
Short answers, pulled from the story.
What year did Max Planck propose quanta to explain blackbody radiation?
Max Planck proposed quanta to explain blackbody radiation in 1900, originating quantum theory. Albert Einstein discovered the photoelectric effect and formulated the theory of relativity between 1905 and 1915.
Who announced detection of a particle consistent with the Higgs boson in July 2012?
CERN announced detection of a particle consistent with the Higgs boson in July 2012. This discovery confirmed all fundamental particles predicted by the standard model.
Which branch of physics examines sound waves beyond human hearing range?
Ultrasonics studies sound waves beyond human hearing range. Acoustics examines how sound is produced, controlled, transmitted, and received while bioacoustics analyzes animal calls and hearing mechanisms.
Why did classical physics theories fail in the first two decades of the twentieth century?
Classical physics theories failed because black-body radiation intensity did not match predictions made by classical thermodynamics. Electron emission from illuminated metals also defied existing explanations.
