The frequency of a green light is 6 x 10^14 Hz, its wavelength is:
Correct answer: B. 500 nm
- A. 5 nm
- B. 500 nm
- C. 5000 nm
- D. 100 nm
Explanation
To find the wavelength of the light, we use the speed of light equation: c = λν Where c is the speed of light in a vacuum, which is approximately 3 x 108 meters per second (m/s).λ (lambda) is the wavelength in meters (m).ν (nu) is the frequency. Rearranging the equation to solve for λ: λ = c / ν λ = (3 x 108 ms-1 ) / (6 x 1014 Hz) λ = (3/6) x 108 ms-1 / 1014 Hz λ = (1/2) x 10-6 m λ = 5 x 10-7 meters So, the wavelength of green light is approximately 5 x 10-7 meters, which is often expressed as 500 nanometers (nm) in the visible light spectrum.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
