This rise and fall intensity of sound is called beats. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. CBSE Ncert Notes for Class 11 Physics Waves. The number of maxima or minima heard in one second is called beats frequency. The phenomena of apparent change in frequency of source due to a relative motion between the source and observer is called Doppler’s effect. 11 class physics project is apply even BE and ME students some physics working project use in some physics labe and some time 11 class physics working project is use in personal tuition. The note of frequency 2n is called second harmonic or first overtone. Need assistance? Sound persists on human ear drums for 0.1 second. • Characteristics of wave The characteristics of waves are as follows: […] Wave number describes the number of wavelengths per unit distance. View Physics Project For Class 11 On Thermodynamics PPTs online, safely and virus-free! where, η is modulus of rigidity and ρ is density of solid. Physics Project Topics and Models. Mechanical Waves Those waves which require a material medium for their propagation, are called mechanical waves, e.g., sound waves, water waves etc. Learn the fundamentals of waves and sound in this unit. The velocity of sound in a gas is inversely proportional to the square root of density of the gas. (ii) When Source is at Rest and Observer is Moving When observer is moving with velocity VO’ towards a source at rest, then apparent frequency. I had worked really hard for searching the best stuff for my project and I hope you'll find this helpful. Class 11 Physics Waves and Sound – Get here the Notes for Class 11 Physics Waves and Sound.

Reply. This wave is called stationary or standing waves. (i) Effect of Pressure The formula for velocity of sound in a gas. This is possible only when you have the best CBSE Class 11 Physics study material and a smart preparation plan. Sound waves are mechanical longitudinal waves and require medium for their propagation. Thanks for the note. [The difference of frequencies should not be more than 10. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Nice notes Reply. Therefore,even and odd harmonics are produced by an open organ pipe. to study heart beats and blood flow in different parts of the body. where, E is coefficient of elasticity of the medium and ρ is density of the medium. ELECTROMAGNETIC WAVES 1. particles on two sides of a node vibrate in opposite phase. At nodes, the displacement of the particles remains minimum, strain is maximum,pressure and density variations are maximum. If Vs, Vi and Vg are speed of sound waves in solid, liquid and gases, then, Sound waves (longitudinal waves) can reflect, refract, interfere and diffract but cannot be polarised as only transverse waves can polarised.
