00:01
The frequency of radio waves are given 99 .7 mhz.
00:07
It means in one second, waves oscillate 99 .7 x 106.
00:18
So, first of all we have to find the wave crest.
00:24
So, wave crest will be 99 .7 x 106.
00:36
Because we are asked in one minute.
00:39
So, in one second it is 99 .7 x 106.
00:44
In one minute, 60 seconds.
00:47
So, we will multiply it by 60 and get the answer.
00:51
So, this is our answer.
00:53
Now, second thing is wavelength...
