what is the frequency, in s⁻¹, of green light that has a wavelength of 499 nm? (c = 3.00×10⁸ m/s)
Answer
Explanation:
Step1: Convert wavelength to meters
Convert 499 nm to m. Since 1 nm = 10^{-9} m, so 499 nm = 499×10^{-9} m.
Step2: Use the formula c = λν
The speed - of - light formula is c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency. We want to find ν, so we can rewrite the formula as ν=\frac{c}{\lambda}. Substitute c = 3.00×10^{8} m/s and λ = 499×10^{-9} m into the formula: ν=\frac{3.00×10^{8}}{499×10^{-9}} s^{-1} ν=\frac{3.00×10^{8}}{4.99×10^{-7}} s^{-1} ν = 6.01×10^{14} s^{-1}
Answer:
6.01×10^{14} s^{-1}
