Frequency-Amplitude: Do Higher Frequencies Mean Higher Amplitude?

AI Thread Summary
Higher frequencies do not necessarily correspond to higher amplitudes in sound waves. The amplitude of sound waves determines their strength or volume, while frequency relates to the pitch. Bats communicate using ultrasonic frequencies, but this does not imply that their sound waves have high amplitude. Amplitude, frequency, and phase are independent characteristics of sound waves and can be specified separately. Understanding these distinctions is crucial in acoustics and sound wave analysis.

Do higher frquencies have higher amplitude? Bats communicate at Ultasonic frequencies. DOes this mean the waves amplitude is very high?

The amlitude of sound waves is independent of
their frequency. The amplitude determines
the strenght (volume) of the waves.

Live long and prosper.
 
For example, in an explosion, it produces a very loud bang. (ie large amplitude) The dull sound it produces indicates the sound wave has low frequency(pitch).
 
We can characterize a sine wave

completely with three quantities, frequency, amplitude and phase. They can be specified separately.

frequency is 1/peroid
that mean how must the peroid in 1 second is the frequency
so the large frequency doesn't mean large amplitude
 
Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
