Calculate the frequency of the red light emitted by a neon sign with a wavelength of 700 nm. A) 2.33 × 10¹⁴s^-1 B) 4.00 × 10¹⁴s^-1 C) 4.29 × 10¹⁴s^-1 D) 5.05 × 10¹⁴s^-1 E) 3.50 × 10¹⁴s^-1

Question

Quizplus · Accepted Answer

The frequency (f) can be calculated using the formula f = c/λ, where c is the speed of light (3.00 × 10^8 m/s) and λ is the wavelength (700 nm = 700 × 10^-9 m). This gives f = (3.00 × 10^8 m/s) / (700 × 10^-9 m) = 4.29 × 10^14 s^-1.
