An echo is just the reflection of sound from a surface. As such it is neither constructive or destructive. These terms refer to the way sound waves combine with each other.

Can be either constructive or destructive. Sound waves?
The terms "constructive" and "destructive", in relation to waves, refer to interference. There can be interference with any kind of waves.
Is seismic waves interference constructive or destructive?
destructive most of the time
Which kind of interference results in bright bands of light?
Constructive Interference
What type of interference occurs when waves meet crest to crest or trough to trough?
No, that would be destructive interference. One crest + one trough = nothing, a flat line.
What is the difference between constructive and destructive interference?
Interference is constructive if the phase difference is zero degrees and destructive if the phase difference is 180 degrees.
What are the two type of inference?
constructive interference destructive interference

Interference is constructive if the phase difference is zero degrees and destructive if the phase difference is 180 degrees.
What are the different types of wave interference?
Constructive, and destructive
Constructive interference occurs when the amplitudes of two waves combine to produce a wave with a smaller amplitude?
It's called Constructive. (:Just found the answer.
Lowest frequency at which destructive interference is observed?
Constructive and destructive interference can occur at any frequency. Superposition of waves is not dependent on a specific frequency.
What type of interference occurs when two waves are in phase?
Constructive
What is constructive and destructive?
Constructive interference can be a confusing concept when called interference. It is wave interference that is moving in phase with another wave. This causes the waves to for a resultant wave with a greater amplitude. Destructive interference is wave interference that is moving out of phase with another wave. These waves form a resultant wave of lower amplitude.
What are two ways that waves are affected by interference?
Constructive and destructive. These are the two extremes.
