The apparent change in frequency/wavelength of a wave caused by a difference in velocity between the source of the wave and the observer is named the Doppler effect or Doppler Shift. Why the Doppler Shift Happens | Doppler effect causes The Doppler shift occurs because a wave is created by a series of pulses at […]

The nature of sound waves | Some important features of sound waves
In this post, we will list down some important features of sound waves (the nature of sound waves). Some important features of sound waves | the nature of sound waves Sound is a longitudinal wave transferred by oscillating molecules so that it needs a medium through which to travel. Sound cannot travel across a vacuum. […]
How to Measure the speed of sound in a laboratory?
Here we will see How to Measure the speed of sound in a laboratory. It is possible to measure wave speed using the equation: speed = distance travelled/time taken The problem with measuring the speed of sound in air is that sound travels quickly. So we must find a way to measure short times accurately […]
