Sound Waves Questions And Answers Pdf Download
The loudness of sound waves does not depend on the frequency of the sound waves. 45 m is the wavelength of a sound wave in a medium with a frequency of 840 Hz and a speed of 380 m/s seconds. In light waves, the oscillations of the electric and magnetic fields are transverse. When you strike the unknown with the 270-Hz fork, the beat frequency is 15 Hz. Hence, velocity changes when a wave goes from one medium to another. A region of slightly more compressed air is followed by a region of slightly less compressed air (called a rarefaction). The large amplitude of sound vibrations will produce a loud sound. If the amplitude of vibration is large, the sound produced is loud. Sound waves questions and answers pdf 2019.
