Standing waves are set up on two strings fixed at each end, as shown in the drawing. The two strings have the same tension and m
ass per unit length, but they differ in length by 0.58 cm. The waves on the shorter string propagate with a speed of 41.9 m/s, and the fundamental frequency of the shorter string is 225 Hz. Determine the beat frequency produced by the two standing waves.
1 answer:
The beat frequency produced by the two standing waves is 13 Hz.
<h3>The wavelength of the shorter string</h3>The wavelength of the shorter string is calculated as follows;
The frequency of the longer string is calculated as follows;
The beat frequency produced by the two standing waves is calculated as follows;

It depends on both of them.
In fact, the projectile begins its motion with an initial velocity of
and an angle of 
. On the y-axis (vertical direction), it is an accelerated motion with acceleration equal to -g (gravitational acceleration). The vertical velocity of the projectile at any time t is given by
and as it can be seen, this depends on both initial velocity and angle.
