LOL you answered it yourself and you want us to find the answer.

Answer 2

$\huge\star\mathfrak\red{{Hey Mate...!!}}$

(1) Frequency = oscillation/Time

Frequency = 40/60

Frequency = 2/3Hz

Frequency = 0.67 Hz

(2) Time period = Time/Oscillation

Time Period = 60/40

Time Period = 3/2sec

Time Period = 1.5sec
