№6.28 (с. 36)
Условие. №6.28 (с. 36)
скриншот условия
6.28 Максимальной чувствительностью глаз обладает в зелёной части спектра. Определите длину волны данной части спектра, если соответствующая ей частота равна 545 ТГц.
Решение. №6.28 (с. 36)
Дано:
Частота света, $\nu = 545 \text{ ТГц}$
Скорость света в вакууме, $c \approx 3 \cdot 10^8 \text{ м/с}$
$\nu = 545 \text{ ТГц} = 545 \cdot 10^{12} \text{ Гц}$
Найти:
Длину волны $\lambda$.
Решение:
Длина электромагнитной волны $\lambda$ связана с ее частотой $\nu$ и скоростью распространения в вакууме $c$ (скоростью света) следующим соотношением:
$c = \lambda \cdot \nu$
Из этой формулы выразим искомую длину волны:
$\lambda = \frac{c}{\nu}$
Теперь подставим известные значения в формулу и произведем расчет:
$\lambda = \frac{3 \cdot 10^8 \text{ м/с}}{545 \cdot 10^{12} \text{ Гц}} = \frac{3}{545} \cdot 10^{(8-12)} \text{ м} \approx 0.0055046 \cdot 10^{-4} \text{ м}$
$\lambda \approx 5.5046 \cdot 10^{-7} \text{ м}$
Для удобства и наглядности результат для видимого света принято представлять в нанометрах (нм), где $1 \text{ нм} = 10^{-9} \text{ м}$. Переведем полученное значение в нанометры:
$\lambda = 5.5046 \cdot 10^{-7} \text{ м} = 550.46 \cdot 10^{-9} \text{ м} \approx 550 \text{ нм}$
Ответ: длина волны данной части спектра равна приблизительно 550 нм.
