Answer:
The speed of the wave is [tex]\bold{3.00 \times 10^8 \ m/s}[/tex].
Explanation:
We are given that a wave has a wavelength of 200 meters and a frequency of 20 Hz.
The equation that relates the speed, wavelength, and frequency is
[tex]c = \lambda \upsilon,\\\text{where c is the speed of light constant,} \\\lambda \ \text{is the wavelength, and}\\ \ \upsilon \ \text{is the frequency of the wave}.[/tex]
Luckily, instead of having to make a calculation, the speed of a wave is a constant. This is the speed of light constant, where [tex]\texts{c = 3.00 \times 10^8 \ m/s}[/tex].
Therefore, instead of having to solve, we can now determine that the speed of the wave is [tex]\small\boxed{\bold{3.00 \times 10^8 \ m/s}}[/tex].
