Practice CBSE Class 11 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 frequencWaves that need a medium to travel through are called:Can mechanical waves travel through a vacuum?Mechanical waves depend on which properties of the medium?Electromagnetic waves are described as being:A wave whose particles oscillate perpendicular to its travel is:A wave whose particles oscillate along its direction of travel is:A wave on a string is given as an example of which wave?The wavelength is the distance between two consecutive:The quantity k is called the angular wave number or:The SI unit of the angular wave number is:When two pulses overlap, the resultant displacement is the:The rule that overlapping waves add is called the principle of:Under superposition, each pulse moves as if the others are:A wave meeting its own reflection can form a wave that is:In a standing wave, points of zero amplitude are called:In a standing wave, points of largest amplitude are called:A stationary wave pattern results from superposing how many waves?The positions of the nodes in a standing wave are:
