Q51.
What does the visual angle represent?

a.

The size of the object

b.

The distance of the object from the eye

c.

The field of view occupied by the object

d.

The angular position of the object in the visual field

Discuss
Answer: (c).The field of view occupied by the object Explanation:The visual angle indicates how much of the field of view is taken by the object.
Q52.
How is visual angle affected by the size and distance of an object?

a.

The larger the object, the larger the visual angle

b.

The further the object, the larger the visual angle

c.

The smaller the object, the larger the visual angle

d.

The closer the object, the larger the visual angle

Discuss
Answer: (a).The larger the object, the larger the visual angle Explanation:If two objects are at the same distance, the larger one will have a larger visual angle. Size influences the visual angle, while distance affects the perceived size.
Q53.
What is the measurement unit for visual angle?

a.

Centimeters

b.

Meters

c.

Degrees or minutes of arc

d.

Pixels

Discuss
Answer: (c).Degrees or minutes of arc Explanation:The visual angle measurement is given in degrees or minutes of arc, where 1 degree is equivalent to 60 minutes of arc, and 1 minute of arc to 60 seconds of arc.
Q54.
What is visual acuity?

a.

The ability to perceive depth accurately

b.

The ability to detect fine detail in visual stimuli

c.

The ability to perceive colors accurately

d.

The ability to recognize objects quickly

Discuss
Answer: (b).The ability to detect fine detail in visual stimuli Explanation:Visual acuity refers to the ability of a person to perceive fine detail in visual stimuli.
Q55.
How is visual acuity typically measured?

a.

By testing the ability to perceive depth cues

b.

By testing the ability to recognize objects at a distance

c.

By measuring the visual angle of an object

d.

By using standardized eye tests to assess perception of fine detail

Discuss
Answer: (d).By using standardized eye tests to assess perception of fine detail Explanation:Visual acuity is typically measured using standardized eye tests that assess the ability to perceive fine detail.
Q56.
According to the law of size constancy, what happens to our perception of an object's size as its visual angle changes?

a.

Our perception of size remains constant

b.

We perceive the object as smaller

c.

We perceive the object as larger

d.

Our perception of size varies depending on the visual angle

Discuss
Answer: (a).Our perception of size remains constant Explanation:According to the law of size constancy, our perception of an object's size remains constant even if its visual angle changes.
Q57.
What cues can be used to determine the relative positions and distances of objects in a scene?

a.

Overlapping of objects and their sizes

b.

Color and brightness of objects

c.

Speed of movement of objects

d.

Texture and patterns on objects

Discuss
Answer: (a).Overlapping of objects and their sizes Explanation:Overlapping of objects and the size and height of objects in the field of view can provide cues to determine their relative positions and distances.
Q58.
What is the relationship between familiarity and perception of an object's size and distance?

a.

Familiarity allows us to perceive an object as larger than it actually is.

b.

Familiarity allows us to judge an object's distance based on its expected size.

c.

Familiarity affects our ability to perceive brightness and contrast in an object.

d.

Familiarity influences our perception of an object's color and saturation.

Discuss
Answer: (b).Familiarity allows us to judge an object's distance based on its expected size. Explanation:Familiarity with an object's expected size can allow us to judge its distance accordingly.
Q59.
What is luminance?

a.

The subjective perception of brightness

b.

The amount of light emitted by an object

c.

The measurement of color intensity

d.

The reflective properties of an object's surface

Discuss
Answer: (b).The amount of light emitted by an object Explanation:Luminance refers to the amount of light emitted by an object.
Q60.
How does luminance affect visual acuity?

a.

Visual acuity decreases with increased luminance.

b.

Visual acuity increases with increased luminance.

c.

Visual acuity is not affected by luminance.

d.

Visual acuity is inversely related to luminance.

Discuss
Answer: (b).Visual acuity increases with increased luminance. Explanation:Visual acuity increases with increased luminance.
