For a concave mirror, when the object is at F, where is the image?
behind mirror, upright, larger, virtual
For a concave mirror, when the object is closer than F, where is the image?
behind mirror, upright, smaller, virtual
What is the only possibility result of a reflection of a convex mirror?
real image
`, an image of an object formed by light rays that actually come together at a specific location
virtual image (behind mirror)
For mirrors, when is di negative?
virtual (upright)
For mirrors, when is hi positive?
real (inverted)
For mirrors, when is hi negative?
upright
For mirrors, when is M positive?
inverted
For mirrors, when is M negative?
Towards
When light enters a more dense material it bends AWAY/TOWARDS the normal
away
2.rule of refraction continued
closer
If an object is underwater, does it appear closer or farther away than it actually is?
90
What is the angle of refraction when light totally internally reflects?
less
Accommodative respone for hyperope is _______ in CL compared to equivalent spectacle correction
binoculars, fiber optics
What are two examples of the usage of total internal reflection?
between F and 2F, inverted, smaller, real
For convex lenses, when the object is beyond 2F, where is the object?
at 2F, inverted same size, real
For convex lenses, when the object is at 2F, where is the image?
beyond 2F, inverted, larger, real
For convex lenses, when the object is between 2F and F, where is the image?
left side of lens, upright, larger, virtual
For convex lenses, when the object is closer than F, where is the image?
Shorter
(Shorter/Longer) wavelengths of light travel slower through ice and, therefore, refract more.
left side of lens, upright, smaller, virtual
What is the only possible result of refraction of a concave lens?
convex lenses
For lenses, when is F positive?
concave lenses
For lenses, when is F negative?
virtual image
a reflected optical image; see "inverted image"
upright image
For lenses, when is M positive?
inverted image
For lenses, when is M negative?
half their height
What is the minimum mirror height that is necessary for a person to see their full image?
greater

yes

water
(fill in the blank) land heats and cools more rapidly and to higher and lower temperatures than _______
not as much light is reflected
Why does a diamond sparkle less in water?
same index of refraction
When will light not refract when it hits a prism?
