Nature Of Light Notes Flashcards
The act or process of deriving a conclusion based solely on what one already knows
Interference
Data collection method used to obtain detailed information about a situation or event
Observation
A pattern plan or representation or description design to show the main object or workings of an object system or concept
Model
What are laws?
They concise general statements about how nature behaves, they are summary of the results of our observations
What are theories?
Once enough observations and laws fall to place these observations and laws become a theory, a theory provides a general explanation for observations in his created to explain these observations
What is the scientific method?
An orderly and systematic approach, gather knowledge
A declaration of conviction, consisting of a sentence of the type I know that or I believe that
knowledge claim
Theories that have a little supporting evidence
Speculative theories
Complex explanatory system that may include presuppositions and miracle evidence, novel, predictions, models, and scientific laws
Robust theory
Consequences deductible from the theory should agree with existing experiments and observations
Accuracy
The theory should be consistent with itself, and other currently accepted theories in other words of theory should not contradict itself or accepted theories
Consistency
The consequences of a theory should extend for beyond the particular observation laws it was initially designed to explain.
Scope
A theory should bring order to phenomena that in its absence could be individually, isolated, and confused
Simplicity
What scientist, combined electricity, magnetism, and light into one theory called the electromagnetic theory of weight
Maxwell
The ratio of speed of light and a vacuum to speed in a given material is called the
Index of refraction
The ratio of speed of light and a vacuum to speed in a given material is called the
Index of fraction
When light passes from one transparent medium into another with a different index of refraction part of it, incident light is reflected at the boundary. The remainder passes into the new media of the ray of light is incident at an angle that is not perpendicular the ray change the direction or _____ as it enters the new medium
refracts
The angle of a fraction depends on the speed of light in the two media, and on the incident angle. a mathematical relationship exist between this quantities known as
Snells law
The photo electric effect is the ejection of what from the surface of metal by light
Electrons
The particle theory of matter is an example of what?
A robust theory
What scientist attempted to measure the speed of light by measuring the time it took for light to travel unknown distance between two hilltops
Galileo
What scientist who is a Danish astronomer who made the first quantitive measurements of the speed of light by studying Jupiter’s moon
Roemer
What scientist express the speed of light as 16 2/3 earth diameters per second
Huygens
What scientist shone a light between the teeth of a rapidly rotating tooth wheel apparatus with a distant mirror
