How does loudness depend on amplitude

The amplitude of a wave does not affect the speed at which the wave travels. Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels. The wavelength of a wave does not affect the speed at which the wave travels.

The amplitude of the sound wave states the loudness of sound. The change in amplitude of the sound wave does not affect the speed of the sound wave. The speed of sound can be affected by the properties of the medium through which it is traveling. Amplitude and sound are directly proportional.

The amplitude of the wave determines the loudness of a sound wave. A larger amplitude means a loud sound while a smaller amplitude means a soft sound. If the amplitude is high then the sound will be louder and the sound will be feeble if the amplitude is low. Amplitude does not affect wavelength. Amplitude is the energy of the wave measured from the rest position to the top of the crest. The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak.

Wavelength is directly related to the frequency of a given wave form. Begin typing your search term above and press enter to search. Press ESC to cancel. Skip to content Home Physics How does loudness of sound is affected by amplitude?

Ben Davis June 23, This activity, as well as enabling an engaging and Classroom Activity Children think about the path which the vibrations must follow from source to detector in order for this sounds to be heard In explaining the properties of light we suggest constructing diagrams based on light rays, which are imaginary. Rays can be Teaching Guidance Sound Wave.
