Explanation:
Gamma rays are the electromagnetic waves that have the highest frequency and the lowest wavelength compared to all other electromagnetic waves.
f = 300 EHz
In terms of frequency the order of frequency is
Gamma rays > X rays > Ultraviolet > Visible > Infrared > high frequency > low frequency > Extremely low frequency
In terms of wavelength the order is the opposite of the frequency
Gamma rays < X rays < Ultraviolet < Visible < Infrared < high frequency < low frequency < Extremely low frequency
4. If you evaporate the water first, then the sand and salt will be nearly impossible to separate. That eliminates 1 and 2. You can't filter salt out from an aqueous solution, so that eliminates 3. 4 works because you can filter out the sand (which doesn't dissolve) then evaporate the water away from the salt.
The equation for density id D=M/V, which is density is equal to mass over volume. The mass (46.8 g) divided by the volume (6 cm^3), is the density. I calculated it to be 7.8 g/cm^3
