لماذا تظهر اطارات السيارة عندما تدور بسرعة كأنها تدور بالعكس؟

17 أبريل 2017

ان ظاهرة رؤية الدواليب او المسننات المتحركة تظهر للناظر ساكنة او متحركة باتجاه
دورانها الحقيقي او باتجاه معاكس هي احدى ظواهر خداع البصر الناتجة عن الإضاءة المتقطعة.

لذلك فإن الدولاب المتحرك يبدو:
1- ساكنا اذا أضيء بتردد مساو لتردد حركته الفعلية.
2- متحركا بنفس اتجاه حركته الفعلية اذا كان تردد الاضاءة اقل من تردد حركته الفعلية.
3- متحركا بعكس اتجاه حركته الفعلية اذا كان تردد الاضاءة اكبر من تردد حركته الفعلية.
