To solve the question, we need to understand what the phase of a particle in simple harmonic motion (SHM) represents. 1. Understanding Simple Harmonic Motion (SHM): - In SHM, the position of a particle can be described by th
allowing movement at an angle. Position is represented as avector, denoted as𝛠, with coordinates (x, y). Displacement, the shortest path between two points, is calculated using the Pythagorean theorem:δr=√(δx^+δy^)and direction viaθ=tan−1(|δy/δx|). Understanding these concep...

The effect occurred over the two-octave range of base speeds studied and well above direction threshold. When the same stimuli were combined with pursuit, observers were able to null the Filehne illusion by adjusting coherence. A power law relating coherence to retinal base speed fit the data ...
