Question

Ashish, Sameer, Aditya and Mohit were sitting on the terrace of Ashish's house listening to the songs playing on Aditya's mobile phone. Mohit, sitting in one corner, a little distance away from the others, requests to increase the volume of the songs. But Aditya says the volume is full. Sameer, being a smart guy, gets up, goes into the kitchen, brings an empty steel glass, places the mobile phone inside it and solves the problem. What is the reason for Sameer to keep the mobile phone in the glass?

Answer 1

The steel glass acts like a small sound box. Sound from the phone is reflected inside the glass and directed outwards, making the music seem louder to Mohit. The glass may also vibrate due to the sound, helping to increase its loudness.
