5 difference between echo and reverberation

1. Echo is a single reflection of a sound wave off a surface. Reverberation is the sound or the pattern created by the superposition of such echoes.

2. An echo can be heard only when the distance between the source of sound and the reflecting body is at least 17.2 m. A reverberation can occur when sound wave is reflected by a nearby wall also.

3. An echo is usually clear and can be clearly distinguished. A reverb is not a clear replica of the original sound sample.

4. Echo can be used to determine the distance of a reflecting object such as a large building or a mountain, if the ambient temperature is known. Reverberation cannot be utilized for distance measurement applications.

5. An echo can be heard both in open and closed spaces. Reverberation is usually experienced in closed spaces with multiple reflecting objects.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
