Question

as changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit

o remain the same

o cannot be determined

o decrease

o increase

Explanation:

Step1: Use the formula \(E = h

u\)
Here, \(E\) is the energy change, \(h\) is Planck's constant (\(h= 6.626\times10^{-34}\space J\cdot s\), a constant), and \(
u\) is the frequency.

Step2: Analyze the relationship

Since \(h\) is constant, from \(E = h
u\), we can express \(
u=\frac{E}{h}\). When \(E\) (energy change) increases, and \(h\) is fixed, \(
u\) (frequency) must increase.

Answer:

increase
