light/ transverse waves, can be refreccted o reflected/ no need of medium , travels in straight directions , the shorter wavelenght the more energy, if the wave is shorter than eyes then is invisible to our eyes
eye/ acomodation, the eye can alter the shape and curvature of the lense to adjust the degree of refraction, is achieved by contraction or relaxion of cilary muscle, far sighted is when eye is to short. The focal point is behind retina, difficult to see close. Convex lenses narrow the planeof light , far sighted is when eye is to short. The focal point is behind retina, difficult to see close. Convex lenses narrow the planeof light
light phenomena/ the angle of incidence is the same as angle of reflection, refraction ocurs when the medium is dense and light pases to the denser medium, can also occur when light passes from a less dense medium to a denser one
artists scientis/ wen you see color you are not necesarrly seeing only one freqquience of light, you may be seeing several hitting your eye with different intensity, your brain interprets and decodes this. White is all precense of all freuencies together.
sound waves/ trevel in different mediums, use particles , quiet= short wavelenght and amplitude, travel fast through solids
to get the speed divide distance by time
to get distance you multiply speed by time
to get time you divide distance by speed
incus; bone in middle ear transmit vibrate in malleus y stapes
stapes; middle in transmit vibrate from incus to inner ear
cochlear nerve; sensory nerve that transfer auditory info from cochlea to brain
vestibo; fluid channels provido into about orientation to brain for balance
hair cell; sensory receptors that detect sount and head motion for balance and hearing control
