heat transfer by touching objects
What is conduction
100
a force that can slow things down, the reason why a sled needs snow
What is friction
100
a material that lets heat and electricity flow through it easily, metal is a good example
What is conductor
100
the light that humans can see
What is visible light spectrum
100
an educated guess about what will happen in the experiment
What is hypothesis
200
the number of cycles per second in a wave
What is frequency
200
the distance between a wave's crest to the next crest -- or trough to trough
What is wavelength
200
heat transfer through liquids or gases
What is convection
200
a wearable head device that filters light to help you see
What is sunglasses
200
develop hypothesis, test hypothesis, collect data, analyze results
What is scientific method
300
an object's acceleration and direction, the rate in which it moves in a certain direction
What is velocity
300
a graphical way of representing a wave
What is sine wave
300
this force makes your hands warm up when rubbed together, and it also can slow things down
What is friction
300
a process that makes light stronger
What is amplification
300
light waves passing through a medium, such as a straw into a glass
What is refraction
400
light amplification by stimulated emission of radiation, a very focused monochromatic beam of light with small divergence
What is laser
400
the energy of movement, such as a baseball flying through the air
What is kinetic energy
400
this form of heat transfer causes a hot dog to cook in a microwave, and has another meaning not relevant to heat
What is radiation
400
a device that came before the laser, it was originally used in microwaves, it was used for microwaves
What is maser
400
this principle makes mirrors work, light waves changing direction
What is reflection
500
a material that lets minimal heat and electricity through, a poor conductor
What is insulator
500
a red slide filters the most of this
What is green light
500
vibrating molecules create this
What is thermal energy
500
he was the creator of the laser, and he made it in 1960
