Answer:

wavelength = 0.8989 m

Explanation:

Given data:

weight of wire is 8.25 g

length of wire is 65 cm

speed of sound in room is 344 m/s

time of returning of pulse is 7.84 ms

There are three time period

Time period $= \frac{7.84\times 10^{-3}}{3} = 2.6133\times 10^{-3} s$

$frequency = \frac{1}{T}$

$=\frac{ 1}{2.6133\times 10^{-3})} = 382.6579 Hz$

velocity = wavelength × frequency

wavelength $= \frac{velocity}{frequency}$

$= \frac{344}{382.6579}$

wavelength = 0.8989 m

The motion of a ball falling through the atmosphere, or a model rocket being launched up into the atmosphere are both excellent examples of Newton’s 1st law of motion.

Riding a bicycle is a good example of Newton’s 2nd law of motion.In this example, the bicycle is the mass. The leg muscles pushing on the pedals of the bicycle is the force.

You hit a wall with a certain amount of force, and the wall returns that same amount of force. This is an example of Newton’s 3rd law of motion

What is a real-life example of destructive interference of light?

34kurt

Destructive Interference. An example of destructive interference is noise canceling headphones. Noise canceling headphones work by using a microphone to pick up the frequencies of incoming waves. The headphone then sends out a wave that is the exact opposite, canceling out the sound.
