Reflected sound is fainter than the original sound because it loses energy each time it bounces off a surface, causing it to decrease in intensity. This energy loss is due to factors such as absorption and dispersion of sound waves as they reflect off surfaces.

What happens to sound if it moves through air into water?

Much of the sound will be reflected (the amount reflected will depend on the angle of incidence). If the angle of incidence is low enough, the sound will be completely reflected. The portion which is transmitted into the water, if any, will be refracted because of the difference in the speed of sound between air and water. Since the speed of sound in water is greater than the speed of sound in air, the sound will be refracted toward the surface of the water. Note that this is the opposite of what happens with light which has a slower speed in water than in air and is refracted away from the surface of the water.


Is a reflected light 90 degrees more than the original one?

No, reflected light is not 90 degrees more than the original light. When light reflects off a surface, the angle of reflection is equal to the angle of incidence, as described by the law of reflection. This means that if the original light beam strikes a surface at a certain angle, the reflected beam will exit at the same angle relative to the normal of the surface, not at an additional 90 degrees.


Why is the intensity of an echo less than that of the original sound?

The intensity of an echo is less than that of the original sound because some of the sound energy is absorbed by the reflecting surface, dispersed, or dissipates while traveling back to the listener. This loss of energy reduces the intensity of the echoed sound compared to the original sound.

No they most definitely do not absorb sound


Sound energy that passes through a solid is said to be reflected?

Sound energy that pass through a solid is said to be reflected because as sound waves pass from air to a solid, some of the energy is reflected back into the air. Some of the energy will be absorbed by the new medium.


What is the magnitude of a star?

Its brightness. the bigger the number, the fainter. So, -1 is brighter than 5.


What things have to happen in order for an echo to happen?

For an echo to occur, sound must be reflected off a hard surface. Additionally, the reflected sound must reach the human ear more than 1/15 of a second after the original sound or the reflected sound will not be able to be distinguished from the original. A true echo is only reflected once.


When a sound from a source is reflected away from the surface of the earth what situation likely exists?

The surface is warmer than the air above it, causing upward refraction.


Why is an echo weaker than original sound?

An echo is weaker than the original sound because sound waves lose energy as they travel and reflect off surfaces, causing a decrease in intensity. Additionally, some of the energy is absorbed by the reflecting surface during the reflection process, further reducing the strength of the echo compared to the original sound.
