Document Summary
Physical science is the study of each and every actual peculiarity we run over in our regular routine. All along, we have found out about the light and sound that we experience without any problem. Researchers through different analyses and perceptions have laid out the way that light and sound are electromagnetic waves that movement in waves. Sound waves require a medium to go while light waves needn"t bother with any medium. It can move as successfully as in air as well as in gasses. You should be generally acquainted with the waves that we see on the water surface when a stone or any item is tossed into it. From that point forward different tests have been directed by numerous researchers to demonstrate this reality however nobody has at any point succeeded. Michelson morley was the pioneer in this field of study.
relative to the observer and if the speed of sound is
, then the perceived frequency 
is related to the actual frequency 
as follows.
past a woman standing on the shoulder of a highway, blowing its horn, which has a frequency of 500 Hz. Assume that the speed of sound is 
. (This is the speed in dry air at
