Doppler effect is related to sound. It describes the change in frequency of sound waves due to relative motion between the source and observer. Approaching objects increase the frequency (higher pitch), while receding objects decrease it (lower pitch), affecting how ...
The ozone layer, located in the Earth’s stratosphere, shields life from harmful ultraviolet (UV) radiation. Human-made substances, such as chlorofluorocarbons (CFCs), contribute to ozone depletion, threatening environmental and health impacts.
In house wiring, three colored wires are typically used: Live (or Phase): Usually red or brown, carries current to the appliance. Neutral: Usually blue or black, completes the circuit. Earth (Ground): Usually green or green/yellow, provides a path for electrical ...
A curved mirror, whether concave or convex, has a focal point where parallel rays either converge (concave) or diverge (convex). This point, called the focal point, is crucial in understanding image formation and optical properties of curved mirrors.
