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 ...

The maximum limit of sound intensity in decibels above which a person cannot hear is 95 dB. This threshold represents the level at which sound becomes too faint for the human ear to detect.
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.
Sound or noise pollution is measured in decibels, a unit that quantifies the intensity of sound. It provides a logarithmic scale to describe sound levels perceived by the human ear.
To hear a clear echo, there should be a minimum distance between the reflecting plane and the sound source of 17 meters. This distance ensures that the time delay between the original sound and its reflected sound is perceptible to ...
The source that causes the most noise pollution among the options provided is Airplane taking off. Aircraft taking off produce extremely high decibel levels, affecting large areas around airports. This surpasses the noise generated by motor vehicles, railway engines, and ...
Sound waves are longitudinal waves. They consist of compressions and rarefactions that travel through a medium, such as air, water, or solids. Unlike transverse waves, which oscillate perpendicular to the direction of wave propagation, longitudinal waves oscillate parallel to the ...
The speed of sound is maximum in solids due to their tightly packed molecules, which facilitate faster sound wave transmission. Among the options, iron has the highest density and rigidity, leading to the fastest speed of sound. Therefore, at 20 ...
The velocity of sound varies across different mediums and is highest in solids. This is due to the tightly packed molecules in solids, which facilitate quicker transmission of sound waves. In contrast, sound travels slower in liquids and slowest in ...
