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
