Physics is an important subject and science students must get a mastery on this. The only way is hard work, reading and understanding the concepts. Here you can test your knowledge. longitudinal waves particles of the medium vibrate perpendicular to direction of propagation of the wave? Two coherent waves propagating simultaneously along same line will interfere constructively if the path difference between them is (2n +1) lTwo identical waves propagating in opposite direction along the same line give rise to stationary waves?
In a closed organ pipe the wavelength of fundamental note is 4 times the length of the organ pipe? When a listener moves away from a sounding source, the pitch of the sound will decrease? If 20 waves passes through the medium in 1 second with speed of 20 ms-1 then wavelength is? The phemenon of passing of waves from one medium into another medium is called? The waves which propagate by the oscillation of material particles are called ………? waves? The waves which do not need a material medium for their propagation are called …………? waves? In longitudinal wave, particles of the medium vibrate ………… to direction of propagation? Number of beats per second is equal to the ………?
Between frequencies of the sources? When a transverse wave is incident on a denser medium from rarer one, it undergoes a phase change of ……… on reflection? The wave which propagate due to oscillation of electric and magnetic field is called? How wavelength and frequency are related with the speed of propagation of a wave?Is it possible for two identical waves traveling in the same direction along a string to give rise to stationary waves?Two waves of slightly different frequencies moving in the same direction along the same line produce beats? How beats are produced?How the velocity of a wave will change if “Tension” is made 16 times?How should a sound source move with respect to observer so that frequency of its sound does not change?
