Ahydrogen atom is in the ground state. it absorbs energy and makes a transition to the n = 6 excited state. the atom returns to the ground state by emitting two photons, one in dropping to n = 5 state, and one in further dropping to the ground state. what are the photon wavelengths of (a) the first and (b) the second transitions?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
