Final answer:
The frequency of the wave is 1.00 × 10⁸ Hz or 100 MHz.
Step-by-step explanation:
The relationship between wavelength (λ) and frequency (f) is given by the equation c = fλ, where c is the speed of light (approximately 3.00 × 10⁸ m/s).
We can rearrange this equation to solve for frequency:
f = c/λ = (3.00 × 10⁸ m/s) / 3 m
= 1.00 × 10⁸ Hz
Therefore, the frequency of the wave is 1.00 × 10⁸ Hz or 100 MHz.
