How could soundwaves be focused by using reflection?
Not all sound that hits matter is absorbed. Some of it is reflected. That means sound bounces off the solid matter the way a tennis ball bounces off a wall. Sound reflected back to its source is an echo.
What happens when light strikes a smooth surface?
When light bounces off something, it is reflected.
What is reflection and refraction of light?
Reflectivity isn't a property of light, it's a property of the surface that reflects the light. It is the proportion of the energy in an incoming light beam which when it hits the surface is reflected rather than absorbed.
When might kinetic energy turn into sound energy?
When you drop a rock and it hits the side walk it makes a sound. Kinetic energy transferred to sound energy.
How is echo useful?
EchoesEchoes are usually used to measure distances for example a "Bat" creates a high velocity sound wave that hits its pray "The Moth" and it comes back with an echo of where abouts it is.Also something called an "Cardioechogram" also, known as a "Cardiogram" is used to measure the heart bps.So Echoes Are An Useful Measuring Device.
The bouncing back or change in direction of a wave after it hits a barrier?
"reflection"
The return of a wave to the medium for which it came when it hits a barrier?
It is reflection.
What happens on sound waves when it hits a barrier?
When waves pass through a narrow gap, be they light or sound, they diffract. This creates an interference pattern of some sort, often depending on the wavelength of the sound and the size of the gap.
When a wave hits a surface through which it CANNOT pass and bounces back it undergoes?
Echo, reprecussion, reverb, reverbration (sound). Reflection (light).
What is the bouncing back of a ray of light sound or heat when the ray hits the surface that it doesn't go through?
We call that "bouncing back" a reflection. Heat in the form of infrared (IR) radiation is like light, and light and sound are said to be reflected off surfaces that do not absorb them.
What term explains why you hear an echo?
when you produce sound, and it hits a barrier, and reflect back. echo is hearing the sound again after the vanish of the original sound. you can only hear it if these two reasons are satisfied: 1) the barrier should be wide (large) enough. 2) distance between source of sound ( the observer) and the barrier is 17 meters or more. OR The easiest answer is that you hear echo by your own ears. DONE BY AHMED HUSSIEN and i thank mr. Ahmed my physics teacher... because without him i wouldn't of had these information....
What type of reflection happens when straight light hits polished wood?
You get both regular reflection and scattered reflection when a straight ray of light hits polished wood.
What kind of reflection occurs when light hits an irregular surface?
diffuse reflection
What is it called where light hits the mirror?
reflection
A beam of light enters a fish tank hits the mirrored surface of the bottom and then comes out at the top what hampens?
reflection, refraction, and reflection occurs because of how the beam of light hits. and where it hits.
What type of reflection happens when a straight ray of light hits smooth mirrors?
When a straight light ray hits a smooth mirror, the regular reflection happens.
What does the word reflection mean When light hits a mirror and bounes reflection Off in a different direction sample mirror We see objects when they reflect light rays into our eyes?
Reflection is when light hits something and bounces back off.
