Using the data in Table 21.1, estimate the dielectric constants for borosilicate glass, periclase (MgO), poly(methyl methacrylate),

Question:

Using the data in Table 21.1, estimate the dielectric constants for borosilicate glass, periclase (MgO), poly(methyl methacrylate), and polypropylene, and compare these values with those cited in the table below. Briefly explain any discrepancies.
Material Dielectric Constant (1 MHz)
Borosilicate glass ................................. 4.65
Periclase ........................................... 9.65
Poly(methyl methacrylate) ...................... 2.76
Polypropylene ..................................... 2.30
