Two sound waves one in air and the other in fresh water are equal in intensity. (a) Find the ratio of pressure amplitude of the wave in water to that of the
A stationary sound wave has a frequency of 165 Hz. If the speed of sound in air is 330 m/s , then the distance between a node and the adjacent antinode is View Solution Stationary waves are setip in an air column. Velocity of sound in air is330ms−1and frequency is165Hz. The di...
23 A stationary wave is formed from two identical sound waves. A microphone is placed at a position of maximum loudness. It is then moved along the stationarny wave from this first position of maximum loudness to the fourth position of maximum loudness.The microphone moves a distance of 12 ...
Two wind instruments produce sound waves with frequencies of 440 Hz and 447 Hz,respectively.How many beats per second are heard from the superposition of the two waves? 答案 会形成拍现象,拍频率为7hz.相关推荐 1Two wind instruments produce sound waves with frequencies of 440 Hz and 447 Hz,res...
What are the two main types of cochlear damage due to loud noises? Cochlea: The cochlea is a significant part of the inner ear which plays a role in hearing as well as in converting sound waves into electrical impulses for the brain to interpret. Due to loud noise, cells in the...
Electrons and chorus waves exchange energy primarily via two types of resonant interactions: cyclotron resonance, which occurs when the Doppler-shifted wave frequency in the particle’s moving frame matches its gyro-frequency,\(\omega - k_\parallel v_c = \omega _{ce}\), and Landau resonance,...
of two Dirac cones associated with the given topology. Furthermore, the robustness of these Dirac cones has been explored in terms of hopping parameters. As an important note, the Fermi velocity of the SG system (vF ≃ c/80) is almost 3.75 times that of the graphene. It has been...

Now the intensity of a wave is the average energy crossing unit perpendicular area per second. This is proportional to the square of the amplitude. Therefore it follows from the superposition principle for displacement that intensities cannot be superposed. When two waves are present the total ...
