Light with a wavelength of 1.5 × 10² m has what frequency? A)2.0 × 10⁶ /s B)0.50 × 10⁶ /s C)2.0 × 10¹⁰ /s D)0.50 × 10¹⁰ /s

Question

Quizplus · Accepted Answer

The frequency ($f$) of light can be calculated using the formula $f = \frac{c}{\lambda}$, where $c$ is the speed of light ($3.0 \times 10^{8} \, \text{m/s}$) and $\lambda$ is the wavelength of the light. Given $\lambda = 1.5 \times 10^{-12} \, \text{m}$, $f = \frac{3.0 \times 10^{8}}{1.5 \times 10^{-12}} = 2.0 \times 10^{20} \, \text{s}^{-1}$.
