Question

A new radio station, KHEM-AM, broadcasts at a frequency of 861 kHz. What is the wave- length of its signal?
Answer in units of meters.

Answer 1

Answer:

Wavelength is 348.43 meter.

Explanation:

We know wavelength×frequency(n)= speed of light at vaccum(c)

→wavelength=c/n

Now given n=861×10³ Hz or s-1

C=3×10^8 m/s

Wavelength=(3×10^8)÷(861×10³) m

=348.43 m
