- The human ear cannot distinguish between two sound notes, the time interval is
- Which of the following statement is true when wave is reflected from denser medium:
- compression is a region of medium where the particles are:
- As a transverse wave strikes against a wall: [CBSE 1997]
- When a gun is fired on the moon the flash of light can be seen but sound cannot be heard because
- Sound energy can be transferred from one place to another place
- When two progressive waves of nearly equal frequencies superimposed and give rise to beats then'
- Three sound waves of equal amplitudes have frequencies (n - 1), n and (n + 1). They are superpose to give beats. The number of...
- The maximum number of beats that can be heard per second is
- The phenomenon of beat is due to
- When two tuning forks are sounded together produce x beats/s. The frequency of A is n_A. The fork B is loaded with little wax...
- To hear beats, it is essential that the two sound waves in air should
- When plane progressive waves travelling in the same direction superpose over each other then the velocity of resultant wave
- The beats are produced by waves of:
- The superposition phenomenon takes place between:
- The superposition takes place between two waves of frequency f and amplitude a. The total intensity is directly proportional to:
- For production of beats the two sources must have: [CBSE 1992]
- A pure sound note is produced by :
- Production of beats is a result of phenomenon of:
- Two tuning forks are sounded together and beats are heard. We can infer that: [CPMT 1975, CPMT 1981]
