    b: Middle
    c: Left
    d: Screwball

6. What is emitted by the hot metal filament in the cathode ray tube?

7. How is the branch of physics that deals with the action of heat and the conversions from one to another of various forms of energy better known?

8. What colour of light will you end up with in each of these two cases if you shine white light through: 
    a: a red filter, then a blue filter
    b: a yellow filter followed by a green filter

9. The energy required to increase the temperature of one pound of water one degree Fahrenheit is known as a Btu. For what does this abbreviation stand?

10. Which early quantum physicist said all matter in motion has a wavelike nature?


1. In metric units, the speed of light in a vacuum is exactly 299,792,458 metres per second (1,079,252,848.8 km/h) but 3?108 m/s is commonly used in rough estimates.

2. Archimedes

3. d: when a car is accelerating. The force causing a car to accelerate comes from a frictional force between the wheels and the road.

4. Eight Answers
    a: Wilhelm
    b: Edwin
    c: Marie
    d: Ernest
    e: Isaac
    f: Max
    g: Niels
    h: Erwin

5. a: Charm

6. Electrons

7. Thermodynamics

8. Two Answers:
    a: Black - You will end up with black light because the red filter only lets red light through, then the blue filter only lets blue light through. However, since the red filter already removed all of the blue light, the blue filter can't let any light through, so you end up with black light.
    b: Green - This is because the yellow filter lets through green and red light (because those are the additive colours of which it is composed), then the green filter only lets through green light. This leaves only green light.

9. British Thermal Unit

10. Louis-Victor-Pierre-Raymond 7th duc de Broglie, generally known as Louis de Broglie (August 15, 1892 ? March 19, 1987) His 1922 doctoral thesis, Recherches sur la th?orie des quanta (Research on Quantum Theory), introduced his theory of electron waves. This included the wave-particle duality theory of matter, based on the work of Einstein and Planck. This research culminated in the de Broglie hypothesis stating that any moving particle or object had an associated wave. Louis de Broglie thus created a new field in physics, the m?canique ondulatoire, or wave mechanics, uniting the physics of light and matter. For this he won the Nobel Prize in Physics in 1929. Among the applications of this work has been the development of electron microscopes with much better image resolution than optical ones. Later, de Broglie worked to develop a causal explanation of wave mechanics, in opposition to the wholly probabilistic models which dominate quantum mechanical theory. Today, this explanation is known as the de Broglie-Bohm theory, since it was refined by David Bohm in the 1950s.
