What is a photon?
protons, neutrons and electrons
What 3 particles make up an atom?
Transverse wave
What is a wave with a direction of propagation that is perpendicular to its direction of oscillation?
Gamma rays
What are the shortest wavelengths on the electromagnetic spectrum?
It has a diameter of 865,000 miles
What is the size of the sun?
Resistance
What is the ability of a material to impede the flow of charge?
Nucleus
What is the center of an atom and contains protons and neutrons?
Supersonic speed
What is any speed that is faster than the speed of sound in the substance of interest?
Electromagnetic wave
A transverse wave composed of an oscillating electric field and a magnetic field that oscillates perpendicular to the electric field is called a ... ?
The core, the radiative zone, the convection zone and the photosphere
What are the four regions of the sun?
Electrical current
What is the amount of charge that travels past a fixed point in an electric circuit each second?
Radioactive
When an atom has too many or too few neutrons?
Pitch
What is the indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave?
Converging lens
What is a lens that focuses horizontally traveling light rays through a single point?
Nuclear fusion
What is the process by which two or more small nuclei fuse to make a bigger nucleus?
Like charges repel one another
What is the first rule of electrical charge?
nuclear force
What is a short-range, attractive force that attracts protons and neutrons to one another?
Inversely proportional
What is the relationship that wavelength and frequency have to one another?
Cone cells in the retina
What are cells that are sensitive to color?
Supernova
The true explosion of a star
Charging by conduction
What is charging an object by allowing it to come into contact with an object that already has an electrical charge?
Isotopes
What are atoms with the same number of protons but different numbers of neutrons?
Amplitude
What governs how loud a sound is?
The Special Theory of Relativity
What says that no object with mass can travel faster than light?
Galaxy
What is a large ensemble of stars, all interacting through the gravitational force and orbiting around a common center
