Understanding the Basics of Wave Speed
Wave speed is a fundamental concept in physics that describes the rate at which a wave propagates through a medium. It is an essential parameter in understanding various phenomena in physics, including sound waves, light waves, and water waves. The speed of a wave can be calculated using the formula: speed = wavelength Γ frequency. In this article, we will explore how to calculate the speed of a wave with a given wavelength and frequency.
Calculating Wave Speed
To calculate the speed of a wave, we need to know its wavelength and frequency. The wavelength is the distance between two consecutive peaks or troughs of the wave, while the frequency is the number of oscillations or cycles per second. In this case, we are given a wavelength of 100 m and a frequency of 25 Hz.
Formula for Wave Speed
The formula for wave speed is given by:
speed = wavelength Γ frequency
where speed is the rate at which the wave propagates, wavelength is the distance between two consecutive peaks or troughs, and frequency is the number of oscillations per second.
Substituting Given Values
Now, let's substitute the given values into the formula:
speed = 100 m Γ 25 Hz
Calculating Wave Speed
To calculate the speed, we multiply the wavelength by the frequency:
speed = 100 m Γ 25 Hz = 2500 m/s
Therefore, the speed of the wave with a wavelength of 100 m and a frequency of 25 Hz is 2500 m/s.
