Answer:
Constructive Interference
Explanation:
Constructive Interference occurs when two waves superimpose and make bigger amplitudes.
In constructive interference, the crests of one wave fall on the crests of second wave and the amplitudes add up. The amplitude of the resultant wave is equal to sum of the amplitude of the individual waves. Similarly, the trough of first wave falls on the trough of other wave and they superimpose to create the trough of the resultant wave.
For Example, In the attachment, two waves A and B superimpose and demonstrate Constructive interference to create the wave C.
Answer:
v = 0.5 m/s
f = 0.42 Hz
ω = 2.6 rad/sec
Explanation:
- By definition, the translational speed is the rate of change of the position with respect to time.
- The change in position along a complete revolution is just the following:
- Δs = 2*π*r = 2*π*0.19 m = 1.19 m
- The time needed to complete a revolution is 2.4 s, so the translational speed can be written as follows:
- The frequency in Hz is just the inverse of the time needed to complete a revolution (known as the period T), as follows:
- f = 1/T = 1/2.4s = 0.42 Hz (2)
- Finally, the angular speed is the rate of change of the angle rotated with respect to time, as follows:
