what is the essential condition for the formation of beats?
a sonometer wire has a length 114 cm between two fixeed ends.where should be two bridges placed so that 3 segments have fundamental frequencies in the ratio 1:3:4?
A transverse wave is described by the equation y=y0 sin2pie (ft-x/a). The maximum particle velocity is equal to 4 times the wave velocity, what is the value of 'a'.
What are standing waves?
a tuning fork of unknown frequency gives 4 beats with a tuning fork of freqency 310 Hz. it gives the same no. of beats on filing. find the unknown frequency
Fundamental frequency of a sonometer wire increases by SHM.If its tension is increased by 21%.How will frequency be affected if its length is increased by 10%.Please give the method. (ans=45.45Hz).
what is doppler effect?
two tuning forks A and B produce 4 beats/sec.On loading B with wax, 6 beats/sec are heard.If quantity of wax is reduced, the number of beats per second again becomes 4.Find the frequency of B if the frequency of B if the frequency of A is 256 hz?
