Two waves of frequencies 480 Hz and 486 Hz interfere. How many beats are heard in 12 seconds?
A stationary wave is given by \( y = 0.05 \sin (\frac{\pi x}{2}) \cos (100\pi t) \), where \( x \) and \( y \) are in meters and \( t \) in seconds. What is the distance between a node and the next antinode?
A pipe closed at one end has a length of 0.4 m and a speed of sound of 320 m/s. What is the frequency of its fundamental mode?
When two waves interfere constructively, what happens to the resultant intensity if their amplitudes are equal?
The speed of sound in air at STP is calculated using Newton’s formula as 280 m/s. If the actual speed is 331 m/s, what is the value of \( \gamma \) (ratio of specific heats) for air?
