Explanation:
- Visual and auditory stimuli both occur in the form of waves. Although the two stimuli are very different in terms of composition, wave forms share similar characteristics that are especially important to our visual and auditory perceptions. Waveforms of different types surround us at all times, however we only have receptors which are sensitive to specific types of wavelengths. In this section, we describe the physical properties of the waves as well as the perceptual experiences associated with them.
AMPLITUDE AND WAVELENGTH
- Two physical characteristics of a wave are amplitude and wavelength (figure below). The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.
The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak.
Wavelength is directly related to the frequency of a given wave form. Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies

In psychology, the term nature refers to traits that
are a result of heredity.
<span>Plato (428–347 BC)
believed that people’s ability to think, feel and interact are innate and
natural. That is, the person already had a set of its characteristics by the
moment he or she was born through his or her genes passed on from his parents.
He believed that people already have the certain tendency to react to a certain
stimulus even before he was taught by his environment.</span>
Answer:
Use clusters of filler materials
Explanation:
A line can be defined as a one-dimensional figure that is straight, has no thickness (width) but extends infinitely in both directions.
Generally, a line can be created through the use of the following techniques or methods;
1. Dot-to-dot placements i.e distance between two points.
2. Use of linear objects: it involves the use of an object that is straight in shape.
3. Sequential placement of materials.
However, a line cannot be created through the use of clusters of filler materials.
