The loudness of a sound depends on its amplitude. If the amplitude of a sound is large, then the sound produced will also be loud. (b) The pitch of a sound depends on its frequency
Therefore, the relationship between f and is inverse: The higher the frequency, the shorter the wavelength of a sound wave. The speed of sound can change when sound travels from one medium to another. ... Since v = f λ v = f λ , the higher the speed of a sound, the greater its wavelength for a given frequency..
Rabies virus is neurotrophic in nature because from the wound of entry, the rabies virus travels quickly along the neural pathways to the central nervous system (CNS). The retrograde axonal transport of the rabies virus to the CNS is the key step of pathogenesis during natural infection
Let
Speed of the wave be c
Wavelength of wave be a
Frequency of the wave be v
Then
c=a*v
