The electromagnetic radiation that will be smartest to use is gamma rays.
<h3>
Electromagnetic radiation</h3>
These are waves that does not require material medium for their propagation.
The wave with high frequency has a greater rate of penetration while those with high wavelength has lesser rate of penetration.
Thus, it will be smart to use the wave with high frequency, which means a low wavelength. The electromagnetic radiation with the highest frequency and low wavelength is gamma rays.

Answer:
Let the mass of mercury m= 13.6 gm and volume be V=1cm3.
Now change in volume when it is heated upto 50oC,
ΔV=VαΔT
ΔV=1×1.82×10−4×50
ΔV=91×10−4cm3
New volume V1=V+ΔV=1.0091cm3
New density ρ=V1m=1.009113.6=13.48gcm−3
