The necessary conditions for hearing an echo can be, The distance between the sound source and the place where it is reflected from must not be less than 17m and the period between hearing the original sound and its echo should not be less than 0.1 of a second.
Q. Why is echo heard?
Echoes. An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. That is why echoes can be heard in a canyon, cave, or mountain range.
Q. What can you do to stop the formation of an echo?
The minimum distance between the source of the sound and the reflector should be at least. 17.2m. The size of the reflector must be large, as compared to the wavelength of the incident sound. The intensity or loudness of the sound waves must be sufficient.
Q. What is Echo God of?
EKHO (Echo) was an Oreiad-nymph of Mount Kithairon (Cithaeron) in Boiotia. The goddess Hera cursed her with just an echo for a voice as punishment for distracting her from the affairs of Zeus with her endless chatter. She was loved by the god Pan, and herself became enamoured of the boy Narkissos (Narcissus).
Q. What is repeated echo called?
When sound, or the echo itself, is reflected multiple times from multiple surfaces, the echo is characterized as a reverberation.
Q. What is an echo in writing?
For writing, an echo is not a yodel bouncing off a distant mountain, rather a repeat of a word or sound that jars the reader. Some examples: The repetition of a common word in close proximity, especially if used in the same position in a sentence or paragraph.
Q. What is the best meaning of her own echo?
An echo is a repetition or imitation of sound. When sound waves hit a hard surface they might reflect, making the sound bounce and repeat. If you agree with someone, you might echo his or her statement.
Q. What is the minimum distance required to hear an echo?
17 m.
Q. How will you calculate the minimum distance from a sound reflecting surface which is necessary to hear an echo clearly?
Since sound has to travel an equal distance in going up to the reflecting surface and in coming back from the reflecting surface, therefore it must travel nearly 33/2 = 16.5 m either way. Thus, to hear the echo clearly in air, the reflecting surface should be at a minimum distance of 16.5 m from the source of sound.
Q. What is the minimum time for Echo?
110 seconds
Q. How can multiple echoes of a single sound be produced?
multiple echoes of a single sound can be produced by the process of reverberation. when a sound reflects multiple times from objects, multiple echoes can be heard.
Q. What does it mean when you say you echo someone?
If you echo someone’s words, you repeat them or express agreement with their attitude or opinion.
