*Use notebook pages 25-36 in addition to pre-quiz from last week to aid in studying*
Wavelength
Crest
*Be able to label the parts of the transverse wave to the right.
Amplitude
1. Categorize a sound wave: Transverse or Longitudinal
2. What is a wave medium? The material a wave can travel through.
3. When pitch increases, so does the FREQUENCY.
Trough
4. Electromagnetic waves need a medium: TRUE or FALSE
Ear Canal
Cochlea
*Label ear structures AND understand their functions (how each works)
Auditory
Nerve
5. Your parents take you to a hearing specialist because you
are having trouble hearing. The doctor does an examination
and finds the fluid in your cochlea is not moving. Being an
expert on the ear, you quickly jump in and explain why this
is most likely happening? The ear drum is not working, which
will then not move the hammer, anvil and stirrup = no fluid movement.
*Know the different types of radiation on the electromagnetic spectrum.
6. Spencer visited the nuclear power plant one day after school when
a siren started going off for hazardous radiation being emitted into
the air. Which type of radiation was most likely the cause of this alarm?
Gamma radiation – it’s hazardous to humans.
Hammer, Anvil &
Stirrup
Pinna
Ear Drum
7. When looking at a light bulb, you are seeing the VISIBLE LIGHT spectrum of the electromagnetic spectrum. It is
broken apart into SEVEN different WAVLENGTHS of color. The combination of all these colors create WHITE LIGHT;
while the absence creates BLACK.
Transparent:
8. How does a blue shirt appear to be blue in color? Shirt absorbs all wavelengths BUT blue, which
is what reflects into our eye. Blue wavelengths are recognized by our cones as BLUE; we see blue!
9. What is diffraction? How does it work? The splitting of white light into individual wavelengths
by passing through a small slit.
10. Besides being diffracted, light can be:
Absorbs
Retina
Iris
Cornea
Optic Nerve
Pupil
Lens
Reflects
Transmitted
Light passes
right through
Translucent:
Scatters and
passes through
Opaque:
Light cannot
pass through
