Noting cloudiness occurs when two solutions are mixed.
The radio waves are electromagnetic wave, so it travels with velocity of light i.e
.
We can use the relation between frequency, wavelength and speed as

Here c is speed of light,
is wavelength and f is frequency and its value is given 99.90 FM, it is actually in megahertz (i.e 99.90 MHz).
Therefore,
.
Thus, the broadcast wavelength of the given radio station is 3.003 m.
In the middle the nucleus is thr brain of it and the electrons spin around the whole atom
Gamma rays are waves of energy that have no charge. TRUE.
