Parts of a Wave
the height of a wave
What is amplitude?
a sound wave is this type of wave that moves side to side
What is a longitudinal wave?
the back part of the eye that receives an image and sends a signal to the brain to interpret that image
What is the retina?
the bending of light from one medium to another
What is refraction?
a curved surface that makes light bend and makes objects appear bigger or smaller
What is a lens?
the highest point or crest of a wave is also called this
What is the peak of the wave?
light waves and water waves fall under this category
What are transverse waves?
the photoreceptors on the retina that are responsible for helping us see color
when light bounces off an object and into our eye
What is reflection?
lenses that curve inward, make light spread out, and makes objects appear smaller (i.e. - a flashlight)
What are concave lenses?
the distance from crest to crest or from trough to trough on a wave
What is wavelength?
the direction that a boat will move when a wave passes underneath it (forward, backward, up and down, or sideways)
What is up and down?
the part of the eye which focuses light onto the back of the retina
What is the lens?
wax paper, sunglasses, a lamp shade, and a pink water bottle
What are translucent objects?
lenses that curve outward, make light waves converge (come together), and make an object appear bigger (i.e. - a microscope)
What are convex lenses?
the number of waves that pass a fixed place in a given amount of time
What is frequency?
the unit of frequency for measuring the number of waves per second
What is hertz?
the photoreceptors on the retina which are sensitive to light
the transfer of energy from light waves to an object
What is absorption?
the type of lens that is in your eye
What is a convex lens?
the two properties of a wave that are inversely related to each other (the higher/longer one is, the lower/shorter the other is)
What are the frequency and wavelength?
the only region of the electromagnetic spectrum that we can see
What is visible light?
the result of the eyeball being too short or too long
What is blurred vision?
red, blue, and green
What are the primary colors of light?
devices with lenses that help us zoom out and in to see objects more clearly
What are microscopes or cameras?
