Light  Particle vs Wave game quiz
"Here it is! The post match analysis of the showdown to decide once and for all whether light is a particle or a wave. Who will be the victor? Play this quiz and be prepared to be taken through the 350 year face-off!"

15 Points Per Correct Answer - No time limit  



1. This 17th century bout began as the two participants entered the ring. In the blue corner was Christiaan Huygens, a Dutch scientist, who argued that light was a wave. Which scientist, who believed light to be a particle, was in the red corner?
    Henry More
    Enrico Fermi
    Isaac Newton
    Louis Pasteur


2. In the pre-match press conference, Newton put forward some convincing arguments for his particle theory. Which word did Newton continuously use to describe these particles of light?
    Bundles
    Corpuscles
    Bags
    Herds


3. There was some pre-existing tension to this contest as Newton and Huygens also disagreed over the way light behaved in a material that was more dense than air. With reference to air, which of the following best describes Newton's theory of the behaviour of light?
    Light travels slower in more dense material
    Light travels faster in more dense material
    There is no change in speed
    Light zig-zags when in more dense material


4. In this confrontation over whether light was a wave or a particle, the bookies had Newton as a clear favourite to win over his opponent, Huygens. Why was this?
    Huygens was a known criminal
    Because of Newton's pre-eminence in science
    Huygens was infamous for his incorrect theories
    Newton was much older and seen as wiser


5. With the crowd behind Newton, he began to pull ahead. However, assistance was given to Huygens by a fellow scientist. This assistance came in the form of the double slit experiment. Which scientist was behind this famous experiment?
    James Franck
    Niels Bohr
    Thomas Young
    Daniel Gabriel Fahrenheit


6. The people in the crowd could hardly believe their eyes as the double slit experiment demonstrated two wave properties of light. One of these wave properties was diffraction. What was the other?
    Deflection
    Compression
    Rarefaction
    Interference


7. Ding ding! Round one was over and Huygens' wave front theory became widely accepted in the world of science. Originally thought to be a longitudinal wave, light was proven to have the same speed as all electromagnetic waves in a vacuum and so was shown to be a transverse wave. Which scientist proved that all electromagnetic waves travelled at the speed 3 x 10^8 m/s?
    James Prescott Joule
    James Clerk Maxwell
    Hendrik Lorentz
    Robert Andrews Millikan


8. In round two of the confrontation to decide whether light was a wave or a particle, Newton now began to fight back. The photoelectric effect proved that light could behave as photons - an idea more consistent with the theory that light was a particle. When these photons hit a metal surface, what could be emitted?
    Positrons
    Pions
    Kaons
    Electrons


9. After the tremendous blows dealt to Newton by his opponent (Huygens) in the first round it meant that he was only able to recover with help from his corner. Which scientist was responsible for explaining the photoelectric effect, thus winning a Nobel Prize and supporting Newton's idea that light was a particle?
    Simon Newcomb
    Albert Einstein
    Georg Ohm
    Wolfgang Ernst Pauli


10. So, where does this leave us? Is light a wave or a particle? It went to a judge's decision and in the end it was up to one judge to deliver the result. The answer is that it is both! A draw! Which scientist suggested that light could show what he called "wave-particle duality"?
    Louis De Broglie
    Michael Faraday
    Max Planck
    James Chadwick
