No, a megaphone is not an example of the reflection of sound. Reflection of sound refers to the phenomenon where sound waves bounce off a surface. A megaphone amplifies sound by directing and focusing the sound waves in a desired direction.
A megaphone amplifies sound by directing and focusing sound waves in a specific direction, making them louder and clearer for listeners.
A megaphone amplifies sound by directing and focusing the sound waves in a specific direction, which results in increased volume and projection. The shape of the megaphone helps to gather sound waves and reflect them forward, making the sound louder to listeners.
A megaphone amplifies sound by capturing and directing sound waves through a cone-shaped structure, which increases the volume of the sound. The shape of the megaphone helps to focus and project the sound waves in a specific direction, allowing the sound to travel over long distances without losing much of its intensity.
An example of transmission of sound would be a person talking through a phone, where the sound waves travel through the phone's material. An example of absorption would be sound being absorbed by a carpeted room, reducing echoes. An example of reflection would be sound bouncing off a hard wall, creating reverberation.
An echo is an example of reflection, which occurs when a wave bounces off a boundary. In the case of sound waves, an echo is produced when sound waves reflect off a surface and return to the listener.

The chemical formula for a megaphone does not exist, as megaphones are not composed of chemical elements but rather made of materials like plastic, metal, or wood. Megaphones are acoustic devices that amplify sound through the reflection and direction of the sound waves.

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.
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
An abat-voix is a device used for reflection of sound, used as a sounding board, for example over a pulpit.

No, a megaphone is a device used to amplify sound, particularly human speech. It does not measure light or speed.
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.
