Multiple Choice
In the context of AP Psychology, what does the term amplitude most accurately refer to?
A
The frequency of a wave, which determines the pitch of a sound
B
The speed at which a wave travels through a medium
C
The distance between two consecutive wave peaks, which determines the wavelength
D
The height of a wave, which determines the intensity or strength of a stimulus such as sound or light
Verified step by step guidance1
Step 1: Understand that in psychology, especially in sensation and perception, waves are often used to describe stimuli such as sound and light.
Step 2: Recognize that amplitude refers to the height of a wave, which is the maximum displacement from the wave's resting position.
Step 3: Know that amplitude is directly related to the intensity or strength of the stimulus; for example, in sound waves, greater amplitude means louder sounds.
Step 4: Differentiate amplitude from other wave properties: frequency (which relates to pitch), wavelength (distance between peaks), and speed (how fast the wave travels).
Step 5: Conclude that amplitude most accurately refers to the height of a wave, determining the intensity or strength of a stimulus such as sound or light.
