Tuning a radio station is an example of resonance. By turning the knob, the radio’s circuit is adjusted to resonate at the specific frequency of the desired station. This resonance amplifies the signal from that station, allowing clear reception of ...

If Tansen’s singing could break window panes or glass glasses, it would be due to resonance. The sound waves from his voice would match the natural frequency of the glass, causing it to vibrate intensely. This amplification of vibrations could ...
We listen to programs of different stations by turning the knob of the radio due to resonance. Tuning adjusts the radio’s circuit to resonate at the frequency of the desired station’s signal. This resonance allows the radio to pick up ...
Polarization is not produced by sound waves in air. Sound waves are longitudinal waves that do not exhibit polarization, which is a property of transverse waves.
The voice of women is generally sharper than that of men because it has a higher pitch. Higher pitch results from higher frequency sound waves, which produce the characteristic sharpness of women’s voices.
Mach numbers are used in relation to the velocity of objects moving through a fluid, most commonly applied to aircraft. It indicates the speed of the aircraft relative to the speed of sound in that medium.
Sonar is mostly used by navigators. Sonar (Sound Navigation and Ranging) is a technology that uses sound waves to detect objects underwater. It is widely employed by navigators, including naval forces, commercial ships, and submarines, to navigate safely, avoid obstacles, ...
The walls, ceiling, and floor of a good auditorium are covered with fibrous materials like carpet and glass fiber to prevent echo by absorbing sound. These materials dampen sound waves, reducing reverberation and ensuring clearer acoustics for the audience. By ...
The working system of radar is based on reflection of radio waves. Radar (Radio Detection and Ranging) uses radio waves transmitted from an antenna. These waves are directed towards an object, and some of them reflect back to the radar ...
The cause of echo is reflection of sound. When sound waves encounter a smooth and hard surface, such as a wall or cliff, they bounce back towards the source. If the reflected sound reaches the listener’s ears distinctively after the ...
