Write an Experiment to verify laws of reflection of sound?
the simple example is stethescope
What is meant by the reflection of sound?
Reflection is the return of sound waves from surfaces on which they are incident.
What is the reflection of sound waves?
The reflection is vibration because sound is equal to vibration
How can you hear a reflection?
Sound can be reflected off things - a reflection of sound is called an "echo" and can be heard.
Application of reflection of sound waves?
1) Megaphones and musical instrumentsà Megaphones or loudhailers, horns, musical instruments are all designed to send sound in a particular direction without spreading it in all directions. In these instruments, a tube followed by a conical opening reflects sounds successively to guide most of the sound waves from the source in the forward direction. 2) Stethoscopeà In stethoscope the sound of a patient's heartbeat is guided by along the tube of the stethoscope to the doctor's ears by multiple reflections of sound. 3) Curved ceilingsà the ceilings of a concert halls, conference halls and cinema halls are made curved so that sound after reflection reaches all the corners of the halls. 4) Sound boardsà in large halls or auditorium, large concave wooden boards are placed behind the speaker. The speaker stands at the focus of this concave reflecting surface. After reflection the sound is spread evenly towards the audience. This makes the sound readily available even at a distance.

What is the principle for megaphone?
The sound is introduced into the narrow end of the megaphone, by holding it up to the face and speaking into it, and the sound waves radiate out the wide end. The megaphone increases the volume of sound by increasing the acoustic impedance seen by the vocal cords, matching the impedance of the vocal cords to the air, so that more sound power is radiated. It also serves to direct the sound waves in the direction the horn is pointing. It somewhat distorts the sound of the voice because the frequency response of the megaphone is greater at higher sound frequencies.

What is an abat-voix?
An abat-voix is a device used for reflection of sound, used as a sounding board, for example over a pulpit.
How does a megaphone work?
Normally sound will spread out in as many directions as it can from a source. As it spreads out with distance, it loses energy (loudness). A megaphone is a cone that limits the directions that the sound can spread into. It concentrates the sound in the forward direction, so that it sounds louder in that direction at longer distances. The tradeoff is that the sound is much quieter off to the sides of the cone than it would be if the megaphone weren't used
How do you make sound louder without a microphone and an amplification system?
We can make sound louder by successive reflection between divergent planes (conical). For example, roll paper into a megaphone or cone shape. Or, cup your hands around your mouth. Additionally, some structures create louder echos. For example, sometimes buildings within a city "bounce" vocalizations, similar to the echo produced in a mountain range or The Grand Canyon.
What is a Non-Example for the word Reflection?
A non-example of the word "reflection" would be an activity or concept that doesn't involve pondering, thinking deeply, or the physical process of light or sound waves bouncing off a surface. For example, playing soccer or painting a picture is not related to reflection. A non-example for the word "reflection" would be something that does not involve the act of reflecting or the phenomenon of light or sound waves bouncing back from a surface. For instance, running a marathon or baking a cake is a non-example of reflection.
What is the function of a megaphone?
megaphones are a device that loud-ens sound to a distance.
What is a difference between a microphone and megaphone?
A microphone translates a sound wave into an electrical impulse, and a speaker translates an electrical impulse into a sound wave.
How can we say that sound also follows the laws of reflection?
Sounds can be reflected, for example, from walls.
What is the function of megahphone?
The main function of a megaphone is to amplify voice/sound towards a targeted direction.
Why I do not have sound from my YouTube?
Your sound is down. Go to the bottom player bar and click the megaphone. Raise the volume or unmute it.
