Question

A source of wave produces a longitudinal wave with a wavelength of 20 meters and a frequency of 10 Hz. What is the speed of this wave?

A) 200 m/s
B) 150 m/s
C) 2 m/s
D) 400 m/s

Answer 1

The speed of the wave can be calculated by multiplying the wavelength by the frequency. In this case, the speed of the wave is A)200 m/s.

Step-by-step explanation:

The speed of a wave can be calculated by multiplying its wavelength by its frequency. In this case, the wavelength is 20 meters and the frequency is 10 Hz. So, the speed of the wave can be calculated as:

speed = wavelength × frequency

speed = 20 m × 10 Hz

speed = 200 m/s

Therefore, the speed of this wave is 200 m/s.
