Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The diagram below represents a wave. If its frequency is 25 Hz, what is the approximate speed of the wave?
A
78 m/s
B
138 m/s
C
160 m/s
D
280 m/s
Explanation: 

Detailed explanation-1: -So, the correct answer is “0.04s".

Detailed explanation-2: -Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

Detailed explanation-3: -2. What is the wavelength of an 18-Hz sound wave in seawater at 25°C? with a wavelength of 1.25 m.

Detailed explanation-4: -What is the frequency of the wave? A wave with a frequency of 14 Hz has a wavelength of 3 meters. At what speed will this wave travel? The speed of a wave is 65 m/sec.
