1. Question
The fill light does which of the following?
a. is the brightest light on the subject
b. shines on the subject's shoulders and hair
c. fills in dark spots which are created
d. lights the background
Answer: c
Explanation: Fill light is used to reduce harsh shadows created by the key light. It softens
contrast and helps reveal details that would otherwise be hidden in darkness. Unlike the
key light, it is not meant to dominate the scene. Its role is supportive and balancing rather
than primary illumination.
2. Question
A spot meter is used to take _____ light measurements.
a. incident
b. task
c. reflected
d. projected
Answer: c
Explanation: A spot meter measures reflected light coming off a subject rather than the
light falling onto it. This allows for precise readings of specific areas within a scene. It is
especially useful in photography and cinematography for controlling exposure. By
isolating small areas, it helps achieve accurate lighting balance.
3. Question
Which of the following stage lighting instruments provides pattern projection
capabilities?
a. PAR64
b. pan and tilt lighting
c. ellipsoidal spotlight
d. adjustable mood lighting
Answer: c
Explanation: An ellipsoidal spotlight is designed with lenses and shutters that allow
projection of patterns, often using gobos. This makes it highly versatile for theatrical
lighting. It can create sharp, focused beams and intricate shapes. Other lighting types
typically lack this level of control.
4. Question
Which of the following stage lighting instruments is used to wash large areas of a stage?
a. PAR
b. gobo
c. barn door
d. ellipsoidal
, Answer: a
Explanation: PAR lights are commonly used for broad, even lighting across large areas.
They produce a wide beam that is ideal for stage washes. Unlike spotlights, they do not
focus on a single subject. This makes them effective for general illumination.
5. Question
What are the primary colors of light?
a. red, blue, and white
b. red, blue, and green
c. red, blue, and yellow
d. red, blue, and black
Answer: b
Explanation: The primary colors of light are red, blue, and green, which form the RGB
color model. These colors combine in different ways to produce the full spectrum of
visible light. When all three are combined at full intensity, they create white light. This
model is fundamental in digital displays and lighting systems.
6. Question
Why is color temperature awareness important in the AV industry?
a. The AV industry strives to set the standard for "whiteness."
b. AV equipment allows for adjusting the "whiteness" for optimal display.
c. People expect exact "whiteness" when viewing a display.
d. "Whiteness" is subjective with ever changing definitions.
Answer: b
Explanation: Color temperature affects how white appears on a display, ranging from
warm to cool tones. AV equipment can be calibrated to adjust this for better visual
accuracy. Proper settings ensure consistency across different devices and environments.
This is crucial for maintaining image quality and viewer experience.
7. Question
The visual field of the human eye is _____ wide.
a. 160 degrees
b. 135 degrees
c. 90 degrees
d. 200 degrees
Answer: a
Explanation: The human visual field spans approximately 160 degrees horizontally. This
wide range allows for peripheral vision, which helps detect movement and spatial
awareness. However, only a small central portion provides sharp detail. Understanding
this is important in display and viewing design.
8. Question
What are the two types of light meters?
a. reading and walking
b. directed and measured
c. projected and monitored
d. incident and reflected
Answer: d
Explanation: Light meters are categorized as incident or reflected. Incident meters
measure light falling onto a subject, while reflected meters measure light bouncing off it.
, Each type serves different purposes in photography and AV setups. Using both can
provide a more complete understanding of lighting conditions.
9. Question
Different colors of light vary in _____.
a. proportion
b. wavelength
c. intensity
d. chromaticity
Answer: b
Explanation: Color differences in light are determined by wavelength. Each color
corresponds to a specific wavelength within the visible spectrum. Shorter wavelengths
appear blue, while longer ones appear red. This property is fundamental to understanding
how light and color work.
10. Question
How many dimensions does color space possess?
a. two
b. five
c. three
d. four
Answer: c
Explanation: Color space is typically represented in three dimensions. These dimensions
correspond to attributes such as hue, saturation, and brightness. This allows for precise
representation and manipulation of colors. It is essential in digital imaging and display
technologies.
11. Question
The source or bulb of the light output is called a _____.
a. display
b. lamp
c. fixture
d. mounting
Answer: b
Explanation: The lamp is the component that produces light in a lighting system. It is the
actual source of illumination. Fixtures and mounts support and direct the light but do not
generate it. Understanding this distinction is important in lighting design and
maintenance.
12. Question
Light energy _____ the farther you get from the source.
a. remains the same
b. spreads out
c. changes color
d. intensifies
Answer: b
Explanation: As light travels away from its source, it spreads out over a larger area. This
reduces its intensity per unit area. This phenomenon is described by the inverse square
law. It explains why objects appear dimmer as distance increases.
