in pressure, i.e. the extent of displacement of the molecules from the position of rest. In Fig. .
the amplitude of sound wave is represented as the distance of Fig. . : Structure of the Human Ear Hammer External canal Anvil Semicircular canals Saccule Utricle Facial nerve Auditory nerve Eustachian tube Round window Stirrup Tympanic membrane Pinna Cochlea the crest or trough from its mean position. Wavelength is the distance between the two crests.
Sound waves are basically formed due to alternate compression and decompression (rarefaction) of air molecules. A complete change in pressure from compression to rarefaction and again to compression makes a cycle of the wave. sound reflects the complexity of its sound waves. Most of the sounds found in natural environments are complex.
Vision and hearing are generally believed to be the two most highly prized senses. What would your life be if you lost any one of your senses? Which sense would you find more traumatic to lose? Why?
Think and write down. What if you could magically improve the performance of one of your senses, which sense would you choose to improve? Why? Could you improve the performance of this one sense without magic?
Think and write down. Discuss with your teacher.
