Question

11 multiple choice 1 point
the wavelength of a lightwave corresponds to which of the following perceptions?
color
volume
pitch
brightness

12 multiple choice 1 point
lina is able to move her hand to the next required position on her guitar neck without looking. which of the following senses contributes the most to this ability?
thermoception
nociception
gustation
proprioception

Explanation:

Analyze light wave properties

Using the Light Wave Properties knowledge point, we examine how physical properties of light map to psychological perceptions. The wavelength of a light wave determines its frequency, which our visual system perceives as hue or color. In contrast, the amplitude (intensity) of the light wave corresponds to brightness. Therefore, wavelength corresponds directly to color.

Evaluate Question 11 options

• color: Correct, as wavelength determines the hue/color we perceive.
• volume: Incorrect, this is an auditory perception related to sound wave amplitude.
• pitch: Incorrect, this is an auditory perception related to sound wave frequency/wavelength.
• brightness: Incorrect, this corresponds to light wave amplitude.

Analyze body position and movement senses

We need to identify the sense that allows someone to know the position of their limbs and move them accurately without visual feedback. This is the sense of body position and movement, known as proprioception (or kinesthesia).

Evaluate Question 12 options

• thermoception: Incorrect, this is the perception of temperature.
• nociception: Incorrect, this is the perception of pain.
• gustation: Incorrect, this is the sense of taste.
• proprioception: Correct, as it provides information about the position and movement of individual body parts.

Answer:

Question 11

• color (Correct answer)
• volume
• pitch
• brightness

Question 12

• thermoception
• nociception
• gustation
• proprioception (Correct answer)
