The wavelength of a certain portion of an electromagnetic wave is 314 nm. What is its frequency and classification? A)9.55 × 10¹⁴ Hz, ultraviolet B)9.55 × 10¹⁴ Hz, X-ray C)8.44 × 10¹⁵ Hz, X-ray D)8.44 × 10¹⁵ Hz, ultraviolet E)9.55 × 10¹⁵ Hz, ultraviolet

Question

Quizplus · Accepted Answer

The frequency is calculated using the formula $ f = \frac{c}{\lambda} $, where $ c $ is the speed of light (approximately $ 3 \times 10^8 $ m/s) and $ \lambda $ is the wavelength. For 314 nm, the frequency is approximately $ 9.55 \times 10^{14} $ Hz, which falls in the ultraviolet range.
