Answer:

Explanation:

99.5 MHz means 99.5 × $10^{6}$ cycles/second.

Electromagnetic radiation (including radio waves) travel at 3.0 × $10^{8}$ meters/second

Wavelength = Speed/Frequency

The wavelength of a 99.5

MHz radio signal is

$\frac{300,000,000}{99,500,000}$ meters (it wont allow to put scientific notation, it is actually 3 ×$10^{8}$/99.5 × $10^{6}$)

= 3.015 meters
