Ответ: в даному випадку вірна відповідь: Б) 45⁰

Объяснение: Під час відбивання світла виконуються два закони відбивання світла: 1) промінь, що падає, промінь відбитий і перпендикуляр до поверхні відбивання, проведений із точки падіння променя, лежать в одній площині; 2) кут відбивання дорівнює куту падіння.

По простому: у даному випадку (попадання проміня на плоске дзеркало), ідеальних умовах кут відбивання дорівнює куту падіння.
