In the above case pump the air out of jar , then allow the sticker to strike the bell.After striking, the bell could be viewed moving but one cannot hear the sound.However if air is pumped back and the experiment is repeated , then one hears sound as well. Lastly it is also used for prenatal scan as it rays are not at all harmful to the women. Note: Download the PDF copy of this set of notes here. You should always remember that that the tuning fork with long prongs produce a sound with lower frequency than the tuning fork with shorter prongs.This is because tuning fork with longer prongs produce sound with long wavelength , hence with low frequency , therefore low pitch and vice versus with that of shorter prongs . describe the production of sound by vibrating sources. 241 0 obj Save my name, email, and website in this browser for the next time I comment.

Hello, my name is Jack Sparrow. endobj Wave motion is the movement and progress of Waves which is the change in state from rest to equilibrium.It can also be defined as the propagation of a wave.Therefore a wave is a disturbance that transfers energy from one point to another which is formed by energy transfer. 0 state the order of magnitude of the speeds of sound in air, liquids and solids. /Prev 400670 The medium is usually air but can be any matter. x�c```b``���dLdd@ A6 da�� ����� ����Ɛ �cid`�0���a�ǂ���5��\�X�;>MȟP���C�J$�����߇�S4��(�y̲�閳. 0000096872 00000 n The surface can also be said to be the locus of points that have the same phase.The wavefront is perpendicular to the ray that represents an electromagnetic waves (EM).

In addition, your name will be written in the credits section of this post. Frequency and time period are inversely proportional (when one increases other decreases) and higher the frequency , the greater the waves. describe the uses of ultrasound in cleaning, quality control and pre-natal scanning. Sound Waves. The ripples reflect through the bar. 1) Sound is produced by vibrating sources placed in a medium. 0000067292 00000 n 227 0 obj Saturday, July 14, 2018. Take a look at the 7 tips to a longer lasting battery! Administrator of Mini Physics. The speed of a wave in water depends on the, depth, so the ripples slow down as they pass over the glass, means they move from deep to shallow. Loudness is related to the amplitude of a 3 Properties of Waves definitions Wavelength ( λ ) is the horizontal distance along a wave between similar particles of the wave. The maximum vertical displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. 0000067916 00000 n 4 0 obj /PageLabels 223 0 R 0000118972 00000 n explain why a medium is required in order to transmit sound waves and describe an experiment to demonstrate this. /L 405330 Hello, I am a Web developer and blogger, currently a UETian, I want to compile all the best O and A level resources at one place for the ease of students. cannot progress through the vacuum because the vacuum has no molecules thus sound cannot progress.It is to note that sound travels fastest in solids followed by liquid and then gas. Notify me of follow-up comments by email. Waves • A wave is a disturbance that pppg gropagates through space and time, usually with trans-ferrance of energy. On the other hand, a transverse wave is a wave where the movement of the medium is at a perpendicular to the wave direction.

From the above picture , where the rope is joined at the one end from tree and is disturbed on the other end by a person , disturbance in medium is created and a wave is formed.The Kinetic Energy from the moving hand is transferred to rope particles which move up and down.In this wave progresses until it reaches the tree.It is to note that the wave direction is perpendicular to the particle vibration direction which is a major property of transverse waves. endobj Lastly you should only only that the the echo is used for echolocation and for measuring large distances. /ViewerPreferences << /Direction /L2R >> <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> ��U&e]�����}�lI���f���0�CE���,J��J2�!

Finally you should also have a knowledge about ultrasound and its uses.Ultrasound are sound waves with frequency higher than 20,000Hz that is the upper limit of audible human hearing range! describe simple experiments to show the reflection of sound waves. CTRL + SPACE for auto-complete. uses cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. Echo is the repetition of sound due to the reflection/bouncing back of sound due to contact with a surface. endobj %���� Thanks heaps! The plane in which the electric and magnetic field vectors lie is tangential to the wavefront at each and every point. Sound Waves are longitudinal in nature primarily due to their parallel particle vibration to wave direction and a series of compression and rarefaction; Sound waves progress and are produced due to series of compression and rarefactions.During the compression , the pressure increases due to closely packed particles and during rarefaction the pressure decreases as particles are spaced away as compared to those of compression.The diagram below explains the scenario : Now when you know about the basics that sound is form of longitudinal wave , you should know that the audible human frequency is between 20 Hertz to 20,000 Hertz.Any sound above or below this range cannot be heard by humans.With growing age , this limit even narrows. From the above image it can be viewed that that with the help of oscillating paddle , disturbances are created in tank , hence wave is produced.When the wave progresses along the ripple tank , the water particles move up and down (showing transverse wave).It is to note that the waves which are produced are only in circular motion but still are perpendicular to the up and down moving water particles.The table shows the moving waves (shadow). 2 0 obj 0000002406 00000 n The larger the amplitude, the louder the sound. 226 0 obj Twitter.
