What is the wavelength of a radio wave with a frequency of 2.00 x 10^4 Hz? (hint: what is the speed of all electromagnetic radiation?)
ОА
6.67 x 105 m
O
B
1.50 x 104 m
6.00 x 1012 m
6.67 x 10m

Option B

The wavelength for a radio wave with a frequency of  2 × 10⁴ Hz is

1.5 × 10⁴ m.

Explanation:

Wavelength is the measure of distance between two successive crests or troughs in a standing wave. Also wavelength can be measured as the ratio of velocity of light to frequency. It is like this because wavelength is inversely proportional to the frequency.

As c = 3 × 10⁸ m/s and the frequency is 2 × 10⁴ Hz, then the wavelength will be

So, the wavelength for a radio wave with a frequency of  2 × 10⁴ Hz is

1.5 × 10⁴ m.
