скриншот условия
3. Согласно Бору при переходе электрона с орбиты, характеризуемой меньшей энергией $E_0$ атома, на орбиту, характеризуемую большей энергией $E_1$ атома, он поглощает электромагнитную волну (фотон) с частотой
1) $(E_1 - E_0)h$
2) $(E_0 - E_1)h$
3) $(E_1 - E_0)/h$
4) $(E_0 - E_1)/h$

Решение. №3 (с. 62)
Решение
Согласно второму постулату Бора, при переходе электрона с одного энергетического уровня на другой атом поглощает или излучает квант электромагнитной энергии — фотон. Энергия этого фотона равна разности энергий уровней, между которыми происходит переход.
В условии задачи электрон переходит с орбиты, характеризуемой меньшей энергией $E_0$, на орбиту с большей энергией $E_1$. Поскольку энергия атома увеличивается ($E_1 > E_0$), он должен поглотить энергию извне. Эту энергию поставляет поглощенный фотон.
Энергия поглощенного фотона $E_{фотона}$ должна быть в точности равна разности энергий конечного и начального состояний:
$E_{фотона} = E_1 - E_0$
В то же время, энергия фотона связана с его частотой $\nu$ (ню) через постоянную Планка $h$ по формуле Планка:
$E_{фотона} = h\nu$
Приравнивая два выражения для энергии фотона, получаем уравнение для частоты:
$h\nu = E_1 - E_0$
Выразим из этого уравнения частоту $\nu$:
$\nu = \frac{E_1 - E_0}{h}$
Это выражение соответствует варианту ответа под номером 3.
Ответ: 3) $(E_1 - E_0)/h$
