Work out the wavelength in Meters with a frequnecy of 300 MHz and speed of 3 × 10^8 m/s.

1 m

Explanation:

The following data were obtained from the question:

Frequency (f) = 300 MHz

Velocity (v) = 3×10⁸ m/s

Wavelength (λ) =?

Next, we shall convert 300 MHz to Hz. This can be obtained as follow:

1 MHz = 10⁶ Hz

Therefore,

300 MHz = 300 MHz × 10⁶ Hz / 1 MHz

300 MHz = 3×10⁸ Hz

Thus, 300 MHz is equivalent to 3×10⁸ Hz.

Finally, we shall determine the wavelength of the as follow:

Frequency (f) = 3×10⁸ MHz

Velocity (v) = 3×10⁸ m/s

Wavelength (λ) =?

v = λf

3×10⁸ = λ × 3×10⁸

Divide both side by 3×10⁸

λ = 3×10⁸ / 3×10⁸

λ = 1 m

Therefore, the wavelength is 1 m

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
