Физика 8 класс. Лаборатория работа. 1. Соберите на планшете электрическую цепь, последовательно соединив источник тока, лампочку, ключ. 2. Расместите в 3-4 см от лампы экран. Луч света, пройдя через щель экрана, должен рас перпендикулярно его плоскости. 3. Вплотную к экрану со стороны, противоположной лампе, положите на планшет лист бумаги, а на него лимб. Обведите на лист бумаги контур лимба. 4. Определите цену деления шкалы лимба. 5. Установите зеркало в центр лимба. При этом поверхность зеркала с отражающим слоем должна располагаться на линии полукруга, нанесённый на лимбе. Нижний край зеркала должен прилегать вплотную к поверхности лимба. 6. С экрана с щелью получите тонкий световой пучок. 7. Направьте световой пучок на зеркало. 8. Определите и запишите в таблицу величины углов отражения и падения света на зеркало в начале опыта. Угол паденияУгол отражения9. Поверните лимб так, чтобы угол падения света на зеркало составил 10 градусов. 10. Измерьте угол отражения. 11. Повторите измерения угла отражения при углах падения в 20 градусов, 35 градусов и 45 градусов. Результат запишите в таблицу ( на фото)​
