Question

In a sinusoidal wave the time required for a particle point to move from maximum displacement to zero displacement is0.14 second the frequency of the wave is

Answer 1

time required for a point to move from maximum displacement to Zero
t=T/4=1/4n
-)n= 1/4t
=
$1 \div (4 \times 0.14) = 1.85$

therefore the frequency is 1.85Hz
