Gravitation
The shape of a planetary orbit.
What is an ellipse?
Properties of a medium that determine the speed of a mechanical wave.
What are rigidity and density?
Two phenomena studied in geometric optics.
What are reflection and refraction?
The two varieties of electric charge.
What are positive and negative?
The scientist who disproved the plum-pudding model of the atom.
Who is Ernest Rutherford?
The scientist who discovered the value of the gravitational constant.
Who is Henry Cavendish?
The change in observed wave frequency due to the relative motion of either a wave source or an observer.
What is the Doppler effect?
380 nm - 750 nm
What is the visible spectrum of light?
The conventional manner of determining the direction of a cross product's vector.
What is the right-hand rule?
The experiment which disproved the plum-pudding model of the atom.
What is the gold-foil experiment?
The instrument used to determine the value of the gravitational constant.
What is the torsion balance?
An interference pattern in which a series of nodes and antinodes form along a medium.
What is a standing wave?
This scientist proved that light was a wave.
Who is Thomas Young?
An electromagnet.
What is a device that uses electric current to produce a magnetic field?
The disconnect between data from blackbody radiation and the prevailing theory about it.
What is the ultraviolet catastrophe?
A phenomenon explained by Einstein's theory of special relativity and the constancy of the speed of light.
What is time dilation?
The condition for a standing wave.
What is that the length of the medium must be a whole-number multiple of half the wavelength of the wave?
This experiment and observation proved that light is a wave.
What are the double-slit diffraction experiment and the interference pattern on the screen?
A device that passes current through a looped wire within a magnetic field in order to elicit a magnetic force to exert a torque.
What is an electric motor?
This was proposed by Max Planck and proven by Einstein.
What is the quantization of energy in light?
An implication about planetary motion derived especially from Kepler's 2nd law.
What is non-constant orbital speed?
An interference pattern in which massive constructive interference occurs due to the source of sound moving at least as fast as sound.
What is a shockwave/sonic boom?
Three ways rainbows form from white light.
What are 1) dispersion; 2) thin-film refraction; and 3) diffraction interference?
An electric generator.
What is a device that rotates a conductive coil relative to a magnetic field to induce a voltage across the conductor and produce a current?
Reasons to attribute uranium's radiation to nuclear activity. (3)
What are 1) its independence from chemical state, temperature, and pressure; 2) its constancy by element, not molecular form; and 3) its 1000-fold higher energy than even ionization?
