Refraction Flashcards
Light doesnt travel in a straight pat
TRUE OR FALSE
False
What happens when light passes from one medium to another?
It bends
The bending or change in direction of light as it passes through different media of different optical densities
Refraction of light
What is optical densities?
Transparency of substance to light
Different materials can change the speed of light in different ways, thus changing its direction
Transparency or opacity
The capability of a medium to change the speed of light can be further identified through the index of refraction
Index of refraction (n)
What is interface?
Where the refraction happens
TRUE OR FALSE
the incident ray, normal, and refracted ray lie on the same plane
True
It is the bending of a wave as it passes through different media
Refraction
When light hits the medium at an angle
Oblique incidence
When light hits the medium perpendicularly
Normal incidence
TRUE OR FALSE
As light travels from a medium with a lower index of refraction to a medium with higher apindex of refraction then ø2 > ø1
False ø2
TRUE OR FALSE
As light travels from a medium with a higher index of refraction to a medium with lower index of refraction then ø2>ø1
True
No bending of light occurs
Normal incidence
