What wavelength does radiation possess when its frequency is 2.1 * 10¹⁵ Hz? A) 4.1 * 10^-7 cm B) 1.4 * 10^-7 m C) 6.5 * 10⁶ m D) 7.0 * 10⁶ m E) 1.4 * 10^-7 nm

Question

Quizplus · Accepted Answer

The wavelength (λ) can be calculated using the formula λ = c / f, where c is the speed of light (approximately 3.0 * 10^8 m/s) and f is the frequency. Substituting the given frequency, λ = 3.0 * 10^8 m/s / 2.1 * 10^15 Hz = 1.428 * 10^-7 m, which is approximately 1.4 * 10^-7 m.
