Question

A radio can tune to any station in 7.5 MHz to 12MHz band. The corresponding wavelength band is

Answer 1

Therefore, the corresponding wavelength band is 40 m - 25 m.

Suppose that the electric field amplitude of an electromagnetic wave is E0 = 120 N/C and that its frequency is v = 50.0 MHz..

Answer 2

Explanation:

Solve the following by both substitution and elimination methods.

$2x - \sqrt{2} y = 0$

and

$\frac{3x}{ \sqrt{2} } - y = 1$
