When White Light is reflected off a red t-shirt some wavelengths are absorbed, leaving you with:
Red Light
Blue Light
Yellow Light
Green Light
A beam of light hitting a mirror at an angle is reflected off at?
Larger angle
Same angle
Smaller angle
Reverse angle
In diffuse reflection, which direction does the light reflect?
In lots of different directions
In one direction
When should you use a neutral density (ND) filter?
When you want extended Depth Of Field or Frozen movement in bright sunlight
To achieve shallow Depth of Field or blurred action in bright sunlight
Which of the following filters describes the Neutral density filter?
darkens the contrast
Cancels your Uber when taking a picture
reduces or modifies intensity of all wave lengths or colors
brightens the saturation
a green object through a red filter appears..
red
green
black
yellow
Lenses are made of......
Flourite
Glass
Glass & Flourite
plastic
Name the type of abberation
Chromatic abberation
Spherical abberation
Optical abberation
There is no abberation
Chromatic aberration occurs because different colors of light
focus at different places after reflection from a mirror
Refract at different angles when passing through a lens
pass through different parts of a lens
all of the above
A polarising filter can
Make a blue sky appear darker
Reduce reflections
Add noise
Make you sleepy
Which of the following is a clear, neutral filter that absorbs ultraviolet radiation, with no effect on visible colours.
UV Filter
Diffusion filter
Spam Filter
Neutral Density Filter
A lens hood helps to prevent....
Bad Focus
Lens Flare
Rain
Good Focus
Light transmission means...
how much light bounces off
how much light shines through
how much light is absorbed
Can absorption, reflection, and transmission of light happen at the same time?
yes
no
Diffuse reflection happens because the surface of most materials are...
smooth
glass
matt / rough
transparent
When white light is transmitted through a red filter. What colour light passes through?
White
Red
All except red
Purple
Can light travel in a curve?
yes
no
In reference to the Inverse Square Law, which of the following is correct?
If the distance of a light from a subject is doubled, the exposure is 1/4
The distance of light from a subject is doubled, the exposure is 1/2
The distance of light from a subject is doubled, the exposure is -4 stops
The distance of light from a subject is doubled, the exposure is +4 stops
