Finding the amplitude with frequency and wavelength.

[sungjoooneee]

A wave with a frequency of 190 Hz and a wavelength of 26.2 cm is traveling along a cord. The maximum speed of particles on the cord is the same as the wave speed.

speed = wavelength X frequency

Ok, so what do you want to calculate? What does the question say, exactly?

To find the amplitude of this wave, we can use the equation for wave speed, which states that speed is equal to the product of wavelength and frequency. In this case, the maximum speed of particles on the cord is equal to the wave speed, so we can rearrange the equation to solve for amplitude.

Amplitude = speed / frequency

Substituting in the given values of frequency and wavelength, we can calculate the amplitude to be approximately 0.138 cm. This represents the maximum displacement of particles on the cord from their resting position as the wave passes through.

It is important to note that amplitude is a measure of the wave's intensity or energy, and it is not dependent on the frequency or wavelength. However, in this case, since the wave speed and maximum particle speed are directly related, the amplitude can be calculated using the given frequency and wavelength values.
