Question

3. Potassium produces a violet flame with a wavelength of 404 nm. Calculate the frequency of this light.
4. Copper produces a green flame. One of the photons it emits has a frequency of 5.77 × 10^14 Hz. Calculate the wavelength of this light in meters.

SnapAndSolve AI · Accepted Answer

To calculate the frequency of light, use the formula: c = λν, where c is the speed of light (3.00 × 10⁸ m/s), λ is the wavelength in meters, and ν is the frequency in Hz. Convert 404 nm to meters: 404 nm = 404 × 10^-9 m. Then, ν = c / λ = (3.00 × 10⁸ m/s) / (404 × 10^-9 m) = 7.43 × 10¹⁴ Hz.
To calculate the wavelength, use the formula: c = λν. Rearrange to find λ: λ = c / ν. Given ν = 5.77 × 10¹⁴ Hz, λ = (3.00 × 10⁸ m/s) / (5.77 × 10¹⁴ Hz) = 5.20 × 10^-7 m.
