What term describes an object that are visible because of reflected light?
An object that is visible because of reflected light is called "luminous" or "reflective."
Why is the sound reflected in mountain area?
This is because sound travels in waves and rebounds off the hard mountains to reach your ears again. There are limited soft objects that absorb the sound, and therefore an echo occurs. This is the reason why you usually only hear a single echo.
Why are ultrasonic waves partly reflected by body organs?
Ultrasonic waves are partly reflected by body organs due to differences in acoustic impedance between the organ and surrounding tissues. This reflection occurs at tissue interfaces with varying densities, leading to partial reflection of the waves.
Why shadow are black?
Shadows appear black because they are areas where light is blocked or absorbed, resulting in less light being reflected. When an object obstructs light, it creates a shadow that appears darker in comparison to the surrounding areas where light is present.
Why do tapping sounds from survivors travel better then shouting?
Tapping sounds travel better than shouting because they are sharper and produce higher frequency vibrations that can travel farther through solid materials like wood or metal. Shouting creates lower frequency vibrations that may be absorbed or muffled more easily.
Why do a shadow form behind the a tree?
We can only see something if light is reflected off it. Our eyes see shadows because there is less light reflected from the shadow than the surrounding area.
What is the nickname of the blue ridge mountains?
The Blue Ridge Mountains are also called the Smokies or Smokey Mountains. Both are because of the color seen through the frequent mist and fog surrounding the mountains. Seen from a distance, the mountains are a smokey blue color.
Why are mountains cooler than the surrounding plains?
Mountains are cooler than the surrounding plains because as elevation increases, the air becomes less dense and can hold less heat. This results in lower temperatures at higher altitudes. Additionally, mountains often receive more precipitation, which can further cool the air through evaporation and cloud cover.
Why do we bring our hands close to mouth while shouting?
Probably because we think it directs the sound towards whatever we're shouting at, or because it may sound louder as it's rebounding off of our hands.
Why does tapping sounds from survivors after earthquakes travel better than shouting for help?
Tapping sounds from survivors after earthquakes may travel better than shouting for help because tapping produces sharp, distinct sounds that can carry well through rubble and debris. In contrast, shouting produces more dispersed and less focused sounds that can be easily muffled by the surrounding environment. Additionally, tapping can create a repetitive pattern that is more likely to stand out and be recognized as a distress signal.
How are mountains and hills alike?
Mountains and hills are both landforms that rise above the surrounding land, but mountains are taller and steeper than hills. Both mountains and hills can provide habitats for various plants and animals, as well as recreational opportunities for people such as hiking and skiing.
How does light reflected?
Light can be reflected because it bounces off a surface at an angle.
Why is a crowd too loud?
Because there are many people talking or shouting in a crowd.
Why is metal unpopular?
Because lots of people think it is just shouting and noise.
Why do students raise their hand in class?
Because it avoids everyone shouting for attention.
Does whisper mean shout?
No, because you cannot whisper while you're shouting
Why residual mountains are also called mountains of denudation?
Residual mountains are also called mountains of denudation because they are formed by the erosion and removal of surrounding material, leaving behind a more resistant core. Over time, the processes of weathering and erosion wear away the softer rocks, exposing the harder rocks as peaks or ridges. This denudation process results in the formation of residual mountains.
