1.	A boat at anchor is rocked by waves of velocity 25m/s, having crests 100 m apart. The boat bounches up once in every …………. .
Answer» `4.0` s 2500 s 0.25 s 75 s Solution :`4.0` s `lambda` = DISTANCE between crests = 100 m frequency `v = (25)/(100) = (1)/(4) s^(-1)` Therefore , the crests REACT the BOAT once every 4 SECONDS .
