I’ll give brainliest! if an observer is hearing a rising pitch, that means that the frequency of the waves in their position is falling. true or false?

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

Consider a hydrogen atom in the ground state. what is the energy of its electron? =e= jj now consider an excited‑state hydrogen atom. what is the energy of the electron in the =5n=5 level? =e5= j

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
