What is the speed of a wave with a frequency of 20 hertz and a wavelength of 2 meters?A 0.1 m/sB 5.0 m/sC 10 m/sD 40 m/s
Question
What is the speed of a wave with a frequency of 20 hertz and a wavelength of 2 meters?A 0.1 m/sB 5.0 m/sC 10 m/sD 40 m/s
Solution
The speed of a wave can be calculated using the formula:
Speed = Frequency x Wavelength
Given: Frequency = 20 Hz Wavelength = 2 m
Substitute the given values into the formula:
Speed = 20 Hz x 2 m = 40 m/s
So, the speed of the wave is 40 m/s. Therefore, the correct answer is D. 40 m/s.
