Question

monocular depth cues include:
convergence and binocular disparity.
color intensity and shape constancy.
amplitude and frequency.
linear perspective and motion parallax.

Explanation:

Monocular depth cues are visual cues that can be perceived with one eye. Convergence and binocular disparity are binocular cues (require both eyes). Color intensity and shape constancy are not primary monocular depth cues; shape constancy is a perceptual constancy, not a depth cue. Amplitude and frequency are properties of waves, unrelated to depth perception. Linear perspective (parallel lines appearing to converge) and motion parallax (closer objects moving faster relative to farther ones) are classic monocular depth cues.

Answer:

Linear perspective and motion parallax.
