Sodium Which spectral line in the sodium line spectrum has the longest wavelength? orange yellow blue O violet

In order for the transition of an electron in a hydrogen atom to produce light visible to the human eye, what must be the final energy level of the electron? O 7 4 1 O 2

Which of the following colors from the visible range has the greatest frequency yellow red orange green O blue Which of the following colors from the visible range has the shortest wavelength green red orange O blue O yellow

Using the Bohr model, pick which electronic transition will emit a photon with the shortest wavelength. Group of answer choices n = 1 → n = 3 n = 2 → n = 1 n = 6 → n = 4 n = 3 → n = 2

The energy of an electron is based on its quantum numbers that define which characteristics? color charge number of electrons distance from nucleus orientation in space shape For the fourth level (n = 4), the subshells that you would find include 12

Convert between number of photons and energy given a particular wavelength. Low level light therapy (LLLT) using RED light was observed to promote wound healing. The daily dose provided was 24 J/cm. Given the wavelength of 635 nm, how many photons were required to deliver the dose to a 1 cm? area?
