Practice JEE Main Waves in the app →A wave on a lake has wavelength $4$ m and frequency $0.5$ Hz. Its speed is:A string of mass per unit length $\mu = 0.01$ kg/m is under tension $T = 100$ N. Wave speed on it is:Two tabla drums sound at $256$ Hz and $260$ Hz simultaneously. The beat frequency heard is:An autorickshaw with horn at frequency $f_0$ moves toward a stationary listener. The listener hears a frequencIf the medium oscillates perpendicular to the direction of propagation, the wave is:If the displacement of the medium is parallel to the direction of travel, the wave is:Waves on a string, water waves and sound waves are examples of which family?Waves that travel from one part of the medium to another are called:Points on a standing wave where the amplitude is zero are called:The lowest possible natural frequency of a system is called its:Transverse waves can propagate only in media that can sustain which stress?Which type of wave can air sustain?When two waves overlap, their displacements add. This is known as the principle of:Wave patterns that do not travel along the medium are called:Points on a standing wave where the amplitude is largest are called:The speed of a transverse wave on a stretched string is set by the properties of the:For a pipe open at both ends, each end behaves as which point?Which harmonics are present in a pipe closed at one end?Laplace pointed out that pressure variations in sound propagation are:How does the Newton formula result for the speed of sound in air compare with experiment?The beat frequency produced by two waves equals which combination of their frequencies?Liquids and solids generally have a speed of sound compared with gases that is:
