Question

In a given medium, wavelength is ______ the frequency for a sound wave.

• A. equal to
• B. inversely proportional to
• C. independent of
• D. directly proportional to

Answer 1

The correct option is B inversely proportional to

$\text{Speed}=\text{Wavelength}\times \text{Frequency}$

For a medium, speed of sound is constant. Hence,
$\text{Wavelength}\propto \frac{1}{Frequency}$
