CERTIFICATION TEST PAPER 2026
COMPLETE QUESTIONS AND SOLUTIONS
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
●● absorbance. Answer: a value that is CALCULATED (not measured)
based on %T to determine how much of the light is absorbed
-%T is measured and then that value is used with a logarithmic equation
to calculate A
-calculated using Beer Lambert law
