Question

An FM radio station broadcasts at 9.23 × 107 Hz. Given that the radio waves travel at 3.00 × 108 m/s, what is the wavelength of these waves? 0.308 m 2.77 m 3.25 m 6.50 m

Answer 1

Answer;

=3.25  m

Explanation and solution;

• The speed of a wave is given by the product of its frequency and wavelength.
• The speed of electromagnetic waves such as radio waves is equivalent to the speed of the light which is 3.00 × 10^8 m/s.

Speed = frequency × wavelength

 3.00 × 10^8 m/s = 9.23 × 10^7 × wavelength

Wavelength = (3.00 × 10^8 m/s)/ (9.23 × 10^7)

                    = 3.25 meters

Answer 2

The result of this question as i think is 3.25m
