Mam kya multiple echos ka application headphones ya earphones me hota h Because earphone me v toh sound tube se pass ho kar aati h just like in Stethoscope.. Mam please tell am I right or wrong.

When distance is equal to displacement?

[@Krishna_Nand_Rai]

When a body move on the straight path

[@nikky2087]

When a body moves in a straight path. Because then the distance from the initial to the final position is same as the displacement.

Thanks mam

[@acquire1238]

Mam wonderful method for teaching science but in echoes please explain distance between us and reflecting surface

[@ashishkushwaha7767]

17.2 metres

[@todobetter2018]

Speed of sound in air at 22°C = 344 m/s. Time after which echo can be heard = 1/10 s or 0.1 second. •: distance b/e the listener = 344 m/s × 1/10 s = 34.4m :. Minimum distance= 34.4/2 = 17.2 m.

Mam straight ceilings per bhi to sound reflect hoti h to fir curved surface kyu banaya

[@aklimakhatun7212]

kyunki jab curved surface Hai to tab agar koi chij uske focus se nikalta Hai to vah sarface Mein ja takra ke use parallel jaate Hain sidha aur Agar vah parallel jaega to Auditorium ka last mein jo baithega vahan tak awaaz jaega aur isse last wale Sun sakte hain aasani se per plane sealing se ye hoga Ki vah pahle Nahin jaega vah upar ki taraf aur niche ki taraf jaega to Jo last Mein baithe honge vah Nahin Sun payenge

[@mohdmukarram8734]

Q mam jab normal ceilings par bhi sound reflect hoti hai to curved ceilings kyu banaye jati hai

[@MagnetBrainsEducation]

Hi there! Thanks for your question. Curved ceilings are often used in schools because the curved shape helps disperse sound more evenly throughout the room. This means that sound does not reverberate as much and makes it easier for students to hear their teachers.

Why reverberation can't be hear in room with all kind of furniture, metal......etc

[@MagnetBrainsEducation]

Hi there! Thank you for your comment and interest in our educational videos. To answer your question, reverberation can be heard in rooms with furniture, metal and other objects because sound waves reflect off of them and create an echo. That's why reverberation can be heard even in a room that has other objects in it. Thanks for watching - keep up the good work!
