DO IT PLS 6. A helium laser emits light with a wavelength of 363 nm. What is the frequency of the light?

the answer for sodium is 0.186

the answer for rubidium is 0.251

i believe the answer is true.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
