Snells Law Flashcards
Index of Refraction formula
n=c/v
What happens when light moves from a material w/ a lower index of refraction to another material with a HIGHER index of refraction? Speed and angle?
Slows down; light bends towards the normal
Positive magnification?
Image is upright/virtual, negative image distance
What type of image is formed when light rays actually intersect?
A REAL image
Focal length for diverging lens
Always negative
Virtual image has what image distance and located where on lens?
Negative, and front
The ____ of light can change when light is refractive bcause the medium changes?
Speed
Refraction is?
The bending of a wave disturbance as it passes at an angle from one medium into another
A magnifying glass is an example of?
Converging lenses
Wave length of light in a medium is larger or smaller than wavelength of light in a vacuum?
Smaller
When light passes from a less dense to a more dense substance, (for example passing from air into water), the light is refracted (or bent) _______ the normal.
towards
If light enters any substance with a higher refractive index (such as from air into glass) it _______.
slows down
If light travels enters into a substance with a lower refractive index (such as from water into air) it speeds up. The light bends ______ the normal line.
away from
