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