What is refraction?
|
The bending of light (changes direction) when it travels from one material to another
|
|
|
What is the angle of refraction?
|
The angle between the refracted ray and the normal line
|
|
|
When the speed of light in the second medium is less than the speed of light in the first medium, what way does the light bend?
|
It bends TOWARDS the normal line
|
|
|
When the speed of light in the second medium is more than the speed of light in the first medium, what way does the light bend?
|
It BENDS away from the normal line.
|
|
|
When some of the light is being reflected, and some of it is being refracted this is called
|
partial reflection
|
|
|
The ratio of the speed of light in a vacuum to the speed of light in a media is called the
|
index of refraction
|
|
|
Index of refraction formula is:
|
n= c / v which is equal to the ratio of n= sin <i / sin <R.
the n is the index of refraction, c is the speed of light in a vacuum ( 3.00) , and v is the speed of light in a given medium |
