What is the relation between the frequency (f) and time period (T) of a sound wave?
f = T
f = \( \frac{1}{T} \)
f = \( \frac{T}{2} \)
f = 2T
This question asks about the fundamental relationship between the frequency and time period of a wave, a basic concept in physics, especially in the study of sound and oscillations. Understanding the definitions of these two terms is key to deriving their relationship.
B) \( f = \frac{1}{T} \). This option correctly represents the inverse relationship between frequency and time period. Frequency is the reciprocal of the time period, meaning that a shorter time period corresponds to a higher frequency, and vice versa.
