We know that a speaker that is 3m away from us is playing music at an intensity of 0.89W/m2. What is the power of this speaker?               Another speaker is playing at an intensity of 1.2W/m2 and a power of 2W. How far away is this speaker from us?                 What is the difference between constructive and destructive interference? Give an example of each.                   If you know that the interference of 2 waves creates a wavelength of a wave is 4.5m, can you determine if the interference is constructive or destructive? How do you know?             If one note has a frequency of 132Hz and another has a frequency of 148Hz.

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
