Express the frequency in inverse seconds. n=5-->n=1

Calculate the frequency of the light emitted when an electron in a hydrogen atom makes each of the following transitions.

n=4 -> n=3

n=5 -> n=1

n=5 -> n=4

n=6 -> n=5

when i did the first one i got 1.60*10^14, which was right, but when i did the second one the same way i got it wrong. could sombody show me how to do it so i can know what im doing wrong?

each time you need to use the same formula: delta E = Efinal -Einitial

Efinal = E1 = -2.18 x 10-18 J / 1^2

Einitl= E5 =  -2.18 x 10-18 J / 1^5

then use E = hv

u should get correct answer unless u r not making any calculation mistake

Explanation:

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
