Practice question

Given: What is the frequency of light with a wavelength of 595 nm in air, given the speed of light in air is 3.0 × 10⁸m/s ? These values define the system as per NCERT data. Formula: Frequency nu = c/lambda. This is standard NCERT relation. Substitution & Calculation: lambda = 5.95 × 10⁻⁷m, c = 3.0 × 10⁸m/s . nu = frac3.0 × 10⁸⁵.95 × 10⁻⁷approx 5.04 × 10¹⁴Hz . Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
