m.
A simple pendulum makes \(10\ oscillations\) in \(20\ seconds\). What is the time period and frequency of its oscillation?
The formula to calculate the
time period
is,
\(Total\ time \times Number\ of\ oscillations\)
\(\frac {Number\ of\ oscillations} {Total\ time}\)
\(\frac {Total\ time} {Number\ of\ oscillations}\)
The formula to calculate the
frequ
ency
is,
\(Total\ time \times Number\ of\ oscillations\)
\(\frac {Number\ of\ oscillations} {Total\ time}\)
\(\frac {Total\ time} {Number\ of\ oscillations}\)
Time period
