Question

state the frequency of seconds pendulum does it depend on the amplitude of oscillation

Answer 1

heya dear your answer is here
______________

Time period of seconds pendulum is 2sec

so f=1/T = 1/2 =0.5Hz

it doesn't depends on amplitude of oscillation

Answer 2

time period of seconds pendulum is 2 seconds. So frequency is
n = 1/T = 1/2 Hz
