As the energy level (n) increases, the energies of successive levels increase. The electron has the highest energy level when it is about to escape the atom. Therefore, the energy is low when n is low, and the energy is high when n is larger.
When the energy difference is higher, more energy is emitted from the electron. This also means the frequency is higher, because it takes more energy to create a wave of higher frequency. Think of it like trying to make waves by shaking a rope. If you move your hands faster and increase the frequency, it takes more energy.
Frequency and Energy are directly proportional to one another. This is because E= hv therefore the change in Energy must also be directly proportional. A higher frequency means a higher energy. This is why UV light has high frequency and high energy.

The SI unit for frequency is Hz (s^-1). However, 1 divided by any unit of time can be used to measure frequency (ex: 1/hr). These are often not seen though because it is impractical for chemistry.
The idea of frequency and energy being proportional is also demonstrated by Bohr's frequency condition (v = delta E/h) which states that only light with certain frequencies (and by extension certain energies) will be absorbed.
