Convex mirrors are used in automobiles to see the rear side traffic. They provide a wider field of view compared to plane mirrors, allowing drivers to see more area behind them. The convex shape makes objects appear smaller but covers ...

The sun appearing red at sunset is not a result of atmospheric refraction. This phenomenon is caused by scattering. As sunlight passes through more of the Earth’s atmosphere at sunset, shorter wavelengths scatter out, leaving the longer red wavelengths to ...
The mirror used by a dentist to check the teeth of a patient is concave. Concave mirrors provide a magnified image, which helps the dentist see a larger and clearer view of the teeth and gums, aiding in better examination ...
Concave mirrors are used in the headlights of vehicles. They focus the light from the bulb into a parallel beam, allowing the light to be directed forward in a concentrated manner, improving visibility for the driver.
Diamond appears shiny primarily due to its high refractive index and strong dispersion of light. When light enters a diamond, it undergoes multiple internal reflections at different angles, enhancing its brilliance and sparkle. This phenomenon is known as diamond’s “fire” ...
The rainbow displays a continuous spectrum of colors. It typically shows seven distinct colors: red, orange, yellow, green, blue, indigo, and violet. This sequence of colors is formed due to the dispersion and refraction of sunlight through water droplets in ...
Cracked glass appears shiny due to reflection. When light encounters the cracked surface, it reflects off the irregularities, creating a shiny appearance. This reflection occurs because the smooth surfaces of the cracks act as mirrors, bouncing light back towards the ...
When light transitions from a denser medium to a rarer medium, such as from glass to air, it can internally reflect. This phenomenon occurs due to the change in the refractive index at the interface. Total internal reflection is crucial ...
Supersonic aircraft produce a shock wave called a “sound boom”. This occurs when the aircraft travels faster than the speed of sound, creating a sudden increase in pressure and temperature. The resulting shock wave is perceived on the ground as ...
The instrument used to identify and draw sound waves is called a “sonar”. Sonar stands for Sound Navigation and Ranging. It emits sound waves into water and detects the echoes bounced back from objects, helping in navigation, communication, and underwater ...
