The Law of Reflection

What is: the angle of reflection is equal to the angle of incidence

This type of solution is What are two The size and position of characterized by water an image formed by a molecules movingof into main ideas plane mirror and out of the cell at thethe cell theory? same rate Daily Double!

What is: same size, same distance from the mirror

The name of the dotted line perpendicular to the surface

What is: the normal

Maintaining conditions The angle of reflection suitable for survival

What is: angle C

The angle of incidence o if angle D is 60

What is: o 30

The bending of light due to a change in speed when moving from one medium to another

What is: refraction

Describes what happens to the How many angle of refraction as light electrons pass travels from a medium with a lower index of refraction to a through a circuit medium with a higher index of in 1 refraction. second?

What is: decreases (bends toward the normal)

The ratio of the speed of light in a vacuum to the speed in a medium; describes the ability of a material to bend light rays Daily Double!

What is: index of refraction

The cause of light being trapped inside a fiber optic

What is: total internal reflection

The name of the minimum angle of incidence required for total internal reflection to occur

What is: critical angle

The sun must be behind you to see a rainbow, and it must reflect off of water droplets in the air

What is: a rainbow

They appear when ice crystals in the atmosphere refract sunlight (as opposed to water droplets for rainbows)

What are: Sundogs

What of is the Strands DNA; An object that appears to be attractive force contain on the ground but is not between water really there directions for molecules called? making protein

What is: a mirage

When light travels through air at different temperatures, it refracts because hot air is less dense than cold air Because there is no distinct boundary between sections of air at different temperatures, the light does not bend at one specific point – it travels along a curved path Daily Double!

What is: Shimmering

An optical effect in which the image of an object appears closer than the object itself

What is: Apparent Depth

Daily Double! The type of lens that converges light rays

What is: a convex lens

The type of lens that diverges light rays

What is: a concave lens

Concave lenses produce these type(s) of images

What is: virtual

Convex lenses produce these type(s) of images

What are: real and virtual

The type of lens used to correct near-sightedness

What is: a concave lens

What is: the cornea

§The structure changes the What is an owl pellet? focal distance of the eye to allow it to focus on objects at various distances

What is: The lens

Daily Double! What causes presbyopia?

What is the: §lenses of the eye become less flexible §ciliary muscles can no longer make the lenses change shape and they turn into very stretched lenses

§far-sightedness (cannot focus on nearby objects) §caused by an eyeball that is too short §the rays reach the retina before they meet §Scientific Name?
