IGCSE Grade 10 Science Speed frequency wavelength and amplitude
|
f= frequency
= wavelength
v = velocity
The presence of medium around the body offers some resistance due to which the amplitude of vibration continuously decreases and does not remain constant.
Wavelength is measured as distance from one compression to the next adjacent compression.
The periodic vibrations of a body of decreasing amplitude in a presence of resistive force are known as damped vibrations.
Sonar stands for sound navigation and ranging.
It is always measured in direction of the wave.
The formula, to find the time period is given below:
It is equal to one wave per second.
Pitch describes how high or low a tone is.
The speed of sound is maximum in solids.
