The brain can retain the impression of the image of an object for 1/20of a second even when the image is no longer in front of the eyes . plz tell me whether it is true or false

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
