The correct answer is d. Wavelength decreases. The principal quantum number (n) describes the size of the orbital. Therefore, the relationship between f and is inverse: The higher the frequency, the shorter the wavelength of a sound wave. This basically means that when the wavelength is increased, the frequency decreas. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. For example, short wavelengths are high energy gamma-rays and x-rays, long wavelengths are low energy radio waves. Scattering of light occurs when light interacts with a particle or surface that is smaller than its own wavelength.
