An echo is returned in `3 s`. What is the distance of the reflecting surface from the source, given that the speed of sound is `342 m//s`.

An echo is heard when minimum distance of the reflecting surface is –

A person clapped his hands near a cliff and heard the echo after 5 s . What is the distance of the cliff from the person if the speed of the sound, v is taken as 346 m//s ?

the minimum distance between the reflecting surface and source for listening the eco of sound is ( take speed of sound 340 m/s )

What is the minimum distance of the obstacle from the source of sound for hearing distinct echo ?

An echo repeats 5 syllables, each of which requires ⅕th of a second to pronounce and ½ second elapses between the time the last syllable is heard and the first syllable is echoed. Is echoed. Calculated the distance of the reflecting surface, the velocity of sound being 332 m//s .

When a sound is reflected from a distant object, an echo is produced. Let the distance between the reflecting surface and the source of sound production remain the same. Do you hear echo sound on a hotter day ?
