You dip your finger repeatedly into water and make waves. If you dip your finger more frequently, the wavelength of the waves
A) lengthens.
B) shortens.
C) stays the same.

Question

Quizplus · Accepted Answer

When you dip your finger more frequently into water, you create waves at a higher frequency. According to the wave equation, velocity (v) = frequency (f) * wavelength (λ). Assuming the velocity of the waves in the water remains constant, an increase in frequency (f) must result in a decrease in wavelength (λ), hence the wavelength shortens.
