Period of 19 Hz Wave with 0.18 m Amplitude & 0.20 m Wavelength

In summary, the 19 Hz frequency in this wave has a calming effect on the human body and mind. The amplitude determines the strength of the wave, and in this case, it is relatively strong with a 0.18 m amplitude. The wavelength and frequency are inversely proportional, and this wave is a transverse wave that requires a medium to travel through. Real-life applications of this specific wave include natural phenomena and technologies such as geophysical exploration and medical ultrasound imaging.

Homework Statement


A wave traveling in the positive x direction with a frequency of 19.0 Hz

The full amplitude of the wave is 0.18 m and the wavelength is 0.20 m

What is the period and speed of the wave?

Homework Equations



speed=(frequency)*(wavelength)
Frequency=1/period

The Attempt at a Solution



I figured the speed by doing 19*0.20 which equaled to 3.8 m/s
For the period, i just did 1/19 and got 0.0526 s but am not too sure about this answer. Please direct me! Thanks!

FAQ: Period of 19 Hz Wave with 0.18 m Amplitude & 0.20 m Wavelength

What is the significance of the 19 Hz frequency in this wave?

The 19 Hz frequency is the number of oscillations per second in this wave. It is a relatively low frequency, which is often associated with calming and relaxing effects on the human body and mind.

How does the amplitude affect the characteristics of this wave?

The amplitude, which is the maximum displacement of the wave from its equilibrium position, determines the intensity or strength of the wave. In this case, the 0.18 m amplitude indicates a relatively strong wave.

What is the relationship between the wavelength and frequency of this wave?

The wavelength and frequency of a wave are inversely proportional, meaning that as one increases, the other decreases. In this case, the 0.20 m wavelength corresponds to a relatively low frequency of 19 Hz.

What type of wave is represented by these parameters?

This wave is a transverse wave, meaning that the particles of the medium move perpendicular to the direction of the wave propagation. It is also a mechanical wave, as it requires a medium to travel through.

What are some real-life applications of a 19 Hz wave with 0.18 m amplitude and 0.20 m wavelength?

This specific wave may be found in various natural phenomena, such as ocean waves or sound waves in a quiet environment. It can also be utilized in technologies that use low-frequency waves, such as in geophysical exploration and medical ultrasound imaging.
