The table shows information about two waves. Based on the given information, which conclusion can be made?
A) Wave X has a greater amplitude.
B) Wave X has a faster speed.
C) Wave W has a faster speed.
D) Wave W has a greater amplitude.
The answer is C) Wave W has a faster speed.
The speed of a wave is determined by its wavelength and frequency. We can calculate the speed of a wave using the equation: speed = wavelength x frequency.
For Wave W, its wavelength is 5 meters and its frequency is 200 hertz. Therefore, the speed of Wave W is 5 meters x 200 hertz = 1000 meters/second.
For Wave X, its wavelength is 3 meters and its frequency is 300 hertz. Therefore, the speed of Wave X is 3 meters x 300 hertz = 900 meters/second.
Since the speed of Wave W (1000 m/s) is greater than the speed of Wave X (900 m/s), we can conclude that Wave W has a faster speed.
