PLEASE HELP........Compare and contrast microwaves with visible light using wavelength frequency and energy.

Microwaves heat up food. Ha just kidding!
Microwaves are lower on the spectrum. They emit less energy and have longer wavelengths. Light Waves emit more energy and have shorter wavelengths than Microwaves. Light Waves can be seen by the naked eye. Both of these waves are harmless and emit low energy, compared to waves higher in the spectrum that have smaller wavelengths, therefore more energy. Some examples are Gamma rays and X-rays, emitting high levels of energy and even radiation.
Hope that makes sense! :V

Answer:
The density of the metal is 5200 kg/m³.
Explanation:
Given that,
Weight in air= 0.10400 N
Weight in water = 0.08400 N
We need to calculate the density of metal
Let be the density of metal and
be the density of water is 1000kg/m³.
V is volume of solid.
The weight of metal in air is
.....(I)
The weight of metal in water is
Using buoyancy force
We know that,
....(I)
Put the value of in equation (I)
Put the value of Vg in equation (II)
Hence, The density of the metal is 5200 kg/m³.
