If Tansen’s singing could break window panes or glass glasses, it would be due to resonance (Option C). Resonance occurs when an object is exposed to sound waves that match its natural frequency. In this case, the glass has a specific natural frequency at which it vibrates. When Tansen sang at a pitch that matched this frequency, the sound waves would cause the glass to vibrate at its natural resonant frequency. This would result in the vibrations being amplified significantly. If the amplitude of these vibrations became too great, the structural integrity of the glass could be compromised, leading to it shattering. This phenomenon is a powerful demonstration of resonance, where even small initial vibrations can build up to destructive levels if the driving frequency matches the natural frequency of the material.

We listen to programs of different stations by turning the knob of the radio due to resonance (Option A). Radios operate by tuning circuits, which consist of inductors and capacitors that can be adjusted to resonate at specific frequencies. When we turn the knob, we are changing the inductance or capacitance, thereby altering the resonant frequency of the circuit. This adjustment allows the radio to select and amplify the electromagnetic waves from a particular station’s broadcast frequency while ignoring others. Resonance occurs when the circuit’s natural frequency matches the frequency of the incoming radio signal, resulting in maximum energy transfer and a clear signal reception. This principle is fundamental in radio technology, as it enables the selective tuning to different broadcast signals, ensuring that we can listen to various stations by simply adjusting the tuning knob to match the desired frequency.

When an army crosses a bridge, soldiers are instructed not to march in step to avoid the danger of the bridge collapsing due to resonance; option [B]. Resonance occurs when the frequency of the soldiers’ synchronized steps matches the bridge’s natural frequency, causing the vibrations to amplify significantly. This can lead to large oscillations and potentially catastrophic structural failure of the bridge. Marching in step, especially if the bridge is long or has a specific structural design, can inadvertently set up these dangerous oscillations. This precaution is crucial because historical incidents have demonstrated that even well-built bridges can succumb to resonant vibrations under synchronized forces. By breaking step, the soldiers create irregular, non-periodic forces on the bridge, which minimizes the risk of resonance and ensures the structural integrity of the bridge remains intact during the crossing.
Sound waves cannot propagate in a vacuum. This is because sound waves are mechanical waves that require a medium, such as air, water, or solid material, to travel through. Sound waves are longitudinal waves, where the oscillation of the particles in the medium is parallel to the direction of wave prRead more
Sound waves cannot propagate in a vacuum. This is because sound waves are mechanical waves that require a medium, such as air, water, or solid material, to travel through.
Sound waves are longitudinal waves, where the oscillation of the particles in the medium is parallel to the direction of wave propagation. Unlike sound waves, light waves are electromagnetic waves that can travel through the vacuum of space without requiring a medium.
The reason sound waves cannot be transmitted through a vacuum is that there are no particles or molecules present in a vacuum to transmit the vibrations that create sound waves. In contrast, electromagnetic waves like light can propagate through the empty space of a vacuum, as they do not rely on the presence of a medium to travel.
Therefore, the correct answer is option (C) Sound, as sound waves are the only type of wave mentioned that cannot propagate in a vacuum.

The photoelectric effect was proposed by Einstein (Option [C]). In 1905, Albert Einstein provided a groundbreaking explanation for the photoelectric effect, where electrons are ejected from a material’s surface when illuminated by light. He proposed that light consists of discrete packets of energy called photons, and each photon transfers its energy to an electron, enabling it to escape from the material. This theory introduced the concept of the photon as a quantum of light and challenged the classical wave theory of light.
Options [A] Compton, [B] Maxwell, and [D] Newton made significant contributions to physics, but they are not credited with explaining the photoelectric effect. Compton is known for the Compton effect involving X-rays, Maxwell formulated Maxwell’s equations describing electromagnetism, and Newton proposed the corpuscular theory of light.
Einstein’s explanation of the photoelectric effect laid the foundation for quantum mechanics and led to further advancements in understanding the dual wave-particle nature of light, influencing modern physics profoundly.
