Visible light consists of electromagnetic waves with wavelengths (in air) in the range 400-700 nm. The speed of light in air is 3.0 × 10⁸ m/s. What are the frequencies of visible light? A) 1.33 × 10¹⁴ Hz to 2.33 × 10¹⁴ Hz B) 1.33 × 10¹² Hz to 2.33 × 10¹² Hz C) 4.29 × 10¹² Hz to 7.50 × 10¹² Hz D) 4.29 × 10¹⁴ Hz to 7.50 × 10¹⁴ Hz

Question

Quizplus · Accepted Answer

The frequency of light is calculated using the formula: frequency = speed of light / wavelength. For visible light, this gives frequencies in the range of 4.29 × 10¹⁴ Hz to 7.50 × 10¹⁴ Hz.
