Light has a frequency of 7.21 × 10¹³ hertz. What is its wavelength? The speed of light is 3.00 × 10⁸ m/s. A) 2.16 × 10⁹ nm B) 2.40 × 10⁵ nm C) 4.16 × 10³ nm D) 2.40 × 10^-4 nm E) 4.16 × 10^-6 nm

Question

Quizplus · Accepted Answer

The wavelength (λ) can be calculated using the formula λ = c / f, where c is the speed of light and f is the frequency. Substituting the given values, λ = (3.00 × 10^8 m/s) / (7.21 × 10^13 Hz) = 4.16 × 10^-6 meters, which is 4.16 × 10^3 nm.
