Problem
The time period of vibration of a stretched string is . Its frequency in kHz is a) 4.0 b) 0.40 c) 0.04 d) 40Intuitive explanation
The core concept here is the reciprocal relationship between period and frequency—they're inverses of each other. Since you're given the time for one complete vibration, you just need to flip it to find how many vibrations happen per second, then convert to the requested unit. This is a straightforward unit conversion paired with a fundamental definition.
