Aradio station's channel, such as 100.7 fm or 92.3 fm, is actually it's frequency in megahertz, where 1 mhz=10^6hz and 1 hz=1s^-1. calculate the broadcast wavelngth of the radio station 99.30 fm.

We can directly solve this problem using the wavelength formula which is:

wavelength = speed of light / frequency

We know from the given that 99.30 FM = 99.30 MHz, therefore:

wavelength = (2.99*10^8 m/s) / (99.30*10^6 Hz) 
wavelength = 3.011 meters

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
