All the points on the string between two consecutive nodes vibrate with a same frequency b same phase c same energy d different amplitude.
Keeping the tension applied same, the length of the wire is doubled. Under what conditions would the tuning form still be is resonance with the wire? What should be the length of a pipe closed at one end, so that Ncert 10th Physics Chapters Video Physics 10th Chapters Video Ncert it also vibrates in its first harmonic with the same tuning fork? If 10th Ncert Physics Book With B is loaded with wax the number of beats is again 5 per second. What is the frequency of the tuning fork B when not loaded? Calculate the resultant amplitude. If the tension in the wire remains Chapters Ncert Physics Video 10th Ncert 10th Physics Chapters Video the same, by what factor will the frequency change?
Which harmonic mode of the pipe is resonantly existed by a source of What is the frequency of the sound for an observer standing on the platform? Interpret what kind of wave this is and find its wavelength. The water level in the tube is gradually lowered.
When the water level is 17 cm below die open end, maximum intensity of sound is heard. The inner core of kin radius is solid. Outside it, there is a region from km to a radius of kin which is in molten Ncert 10th Physics Chapters Video state. Then again from kin to km die earth is solid. Only longitudinal P waves can travel inside a liquid. An earthquake occurs at some place close to the surface of die earth. Calculate 10th Physics Video Ncert Chapters the time after which it will be recorded in a seismometer at a diametrically opposite point on the earth if wave travels along diameter?
