eon\ lights work in a similar way to the flame test, with the input of energy being supplied by electricity instead of a flame. calculate the energy of an orange light emitted by a neon sign with a frequency of 4.89 × 10¹⁴ hz. show your work.

Explanation:

Question 6

The relationship between frequency (\( f \)) and energy (\( E \)) of a photon is given by the equation \( E = hf \), where \( h \) is Planck's constant (\( h = 6.626\times10^{-34}\, \text{J·s} \)). From this formula, we can see that energy is directly proportional to frequency. So as frequency increases, energy increases, and as frequency decreases, energy decreases.

An electron reaches the excited state when it absorbs energy (such as energy from heat, light, or electricity). This absorbed energy causes the electron to move from a lower - energy orbital (ground state) to a higher - energy orbital.

When an electron returns to the ground state from the excited state, it releases the excess energy it had absorbed. This energy is often released in the form of a photon (a particle of light). The energy of the photon corresponds to the energy difference between the excited state and the ground state.

Answer:

As frequency increases (or decreases), energy increases (or decreases) (since they are directly proportional, following \( E = hf \))
