Wavelength is determined by _________.

Wavelength is determined by _________.

• A. The Source
• B. The Medium
• C. Both The Source And The Medium
• D. Neither

Answer: (C)

Wavelength comes from the relationship lambda = v / f, which links how fast the wave travels in a medium (v) with how often it is produced (f). The source sets the frequency, while the medium determines the propagation speed based on its properties. Because wavelength depends on both speed and frequency, changing either the source or the medium changes the wavelength. In a given medium, a higher source frequency yields a shorter wavelength; in a given source, moving to a medium where waves travel faster yields a longer wavelength. So both the source and the medium determine wavelength.
