00:06The speed of a wave in a certain medium is 960 meter per second.
00:14If 3600 waves pass over a certain point of the medium in 1 minute, the wavelength is
00:25a, 2 meters, b, 4 meters, c, 8 meters, d, 16 meters.
00:35As we know that, v is equal to lambda into f.
00:42This is the formula to calculate wave velocity or speed of waves.
00:51So, first of all, we will find frequency, which is not given.
01:02As we know that frequency is also calculated by using formula, number of waves per unit
01:12time, means number of waves passing per unit time is also known as frequency.
01:23Here, the number of waves is given is 3600 divided by time, which is obtained is 1 minute.
01:40So, this zero will be get cancelled with this zero.
01:47The table of 6 on 6 is 1 times and on 360 is 60 times.
01:54So, frequency is obtained as 60 hertz.
02:05Now finally, we will find wavelength is lambda is equal to V upon F. Because here F is multiplying
02:23on the other side of equal, it will divide.
02:26So, this formula will become is.
02:30As we know that, wave velocity is obtained as 960 meter per second divided by frequency,
02:36which is obtained as 60 hertz.
02:38So, 960 divided by 60, it will be equal to 16 meter.
02:48So this is our required answer.
02:52So, the correct option will be D, 16 meter.
03:01So, the Queen's mustache will be used for the older people.
03:02So, the Queen's mustache will be used for the older people from the older people of the
