ACTUAL QUESTIONS WITH HIGHLY
DETAILED VERIFIED CORRECT ANSWERS
EXPERTLY STRUCTURED GRADED A+
⩥ amplitude. Answer: the height of a wave
⩥ frequency. Answer: the number of waves which pass by a stationary
point in one second
-is related to speed
⩥ lower (fill in the blank). Answer: longer wavelegnths are associated
with being (higher / lower) in energy
⩥ visible spectrum. Answer: the portion of the electromagentic spectrum
which produces wavelegnths that can be seen by the naked eye
-red: longest wavelegnth, lowest energy
-violet: shortest wavelength, highest energy
,⩥ electromagnetic spectrum. Answer: HIGHEST ENERGY (short
wavelength)
-cosmic
-gamma rays
-X rays
-ultraviolet
-visible (Violet, blue, green, yellow, orange, red)
-infrared
-microwaves
LOWEST ENERGY (long wavelegnth
⩥ short (fill in the blank). Answer: high frequency= high energy =
____________ wavelengths
⩥ long (fill in the blank). Answer: low frequency= low energy=
_____________ size wavelengths
⩥ reflected light. Answer: light that encounters a solution and is forced
to bounce back in the direction it came from
-does not travel through the solution
⩥ absorbed light. Answer: light that enters a solution, and is absorbed by
the material
,-the light comes into the solution does NOT pass through the solution
⩥ transmitted light. Answer: light that enters the solution is able to pass
through the solution
-light comes into the solution and passes through
⩥ diffracted light. Answer: light that enters a solution and changes
direction
-light bounces out of the solution at an angle
⩥ fluoresced light. Answer: light that enters a solutions and becomes
absorbed, and then emitted at a different (usually longer and visible)
wavelegnth
⩥ transparent. Answer: all light is able to pass through
-a clear substance that allows all light through
⩥ translucent. Answer: some light is able to pass through
-a cloudy substance that does not let all light through
⩥ opaque. Answer: no light passes through
-a VERY hazy solution that lets no light through
, ⩥ diffraction. Answer: white light is sent through a slit (diffraction
grating) and the slit causes bending of light (change in direction of light
beam), which reveals all visible wavelengths of light to be seen
-long wavelengths (low energy, like red) bend the least
-short wavelengths (high energy, like blue) bend the most
⩥ percent transmittance (%T). Answer: Bouguer's Law
- light transmitted / original light
-when more light is absorbed, there is naturally less light that is being
transmitted
⩥ inverse (fill in the blank). Answer: light transmittance (T) and
absorbance have a ___________ logarithmic relationship
-the more light that is absorbed, the less light there is left to be
transmitted
⩥ absorbance assumptions. Answer: to read absorbance 2 factors are
assumed
-monochromatic light: it is assumed that only a single wavelength of
light is being used
-logarithmic relationship: as absorbance increases the %T (%
transmission of light) goes down logarithmically
