Question: User: Visual Prompt for AI Video Generator:Prompt: A clean 2D/3D animated coordinate grid displaying a continuous Sine wave moving smoothly to the right . Glowing markers highlight the highest points labeled "Crest" and lowest points labeled "Trough" . A double-headed horizontal arrow spans from one crest to the next consecutive crest, labeled with the Greek letter lambda (λ) and text "Wavelength" . Clean educational background, precise mathematical annotations .English Voiceover & Text:Voiceover: "If a source vibrates sinusoidally, it creates a repeating sine wave. The highest points are called crests, and the lowest points are called troughs. The wavelength, denoted by lambda, is the distance between two consecutive identical points in phase, such as from crest to crest, measured in meters."
