Visible light with a wavelength of 550 nm has a frequency of ________ Hz. A)5.5 × 10⁵ B)1.7 × 10¹¹ C)5.5 × 10¹⁴ D)1.7 × 10² E)5.5 × 10¹⁷

Question

Quizplus · Accepted Answer

The frequency of light can be calculated using the equation f = c/λ, where f is the frequency, c is the speed of light (approximately 3.00 × 10^8 m/s), and λ is the wavelength in meters. Converting the wavelength of 550 nm to meters, we get 5.50 × 10^-7 m. Plugging this value into the equation, we get f = (3.00 × 10^8 m/s)/(5.50 × 10^-7 m) = 5.45 × 10^14 Hz. The closest answer choice is C, 5.5 × 10^14 Hz, which matches our calculated frequency to the nearest significant digit.
