Question number: 119

» Oscillations and Waves » Periodic Motion - Period Frequency

Assertion-Reason▾

Assertion (Ꭺ)

The periodic time of a hard spring is less compared to that of a soft spring.

Reason (Ꭱ)

The periodic time depends upon the spring - constant, and spring constant is large for hard spring.
