3/4/2023 0 Comments Soundwaves definition![]() Sound Waves are longitudinal waves while Light waves are transverse waves.Question 4: Explain how the characteristics of a sound wave and a light wave differ from each other?ĭifference between the characteristics of sound wave and light wave, Hence, The time period of the first wave more than the Time period of the second wave. The Time period for the second wave= 1/frequency The Time period for the first wave= 1/frequency Question 3: Two waves having Frequencies of 10Hz and 50Hz are given. Hence, the frequency of the wave always remains the same.Īs the formula known for the frequency of the wave is, Frequency is that parameter of the wave which does not change by changing the medium of the propagation. The SI unit of frequency is Hertz (Hz) and it is represented as the symbol nu (ν). The frequency of the wave can also be defined as the number of vibrations created by the wave in one second. The frequency of the sound wave is defined as the number of cycles completed by the wave in 1 second. ![]() Time period is also used to find out the frequency of the wave, the reciprocal of the time period gives the frequency of the wave. One cycle of the wave is defined by one complete rarefaction and compression in the vibration. The Time period of a sound wave is defined as the time required for one complete cycle. The sound wave is longitude in nature, and the combination of the distance of one complete rarefaction and compression gives wavelength. The wavelength is actually a length parameter, hence, the SI unit of wavelength is meter. Note: The wave shown above is a transverse wave, but sound waves are known to be longitudinal in nature, they represented in longitudinal form for better understanding of the conceptsĪ Wavelength is defined as the minimum distance covered by the Wave before it starts repeating itself. ![]()
