Question

Superimposing two identical transverse waves that are in phase is an example of:

A. destructive interference
B. constructive interference
C. resonant subjugation
D. Doppler effect
E. natural frequency overlay

Answer 1

if they're the identical then it's constructive interference

Answer 3

Here's another diagram to help you understand

Constructive interference: http://buphy.bu.edu/~duffy/PY105/35a.GIF
This wave is identical, both are up, so they add to each other a+b when they intersect.

Destructive interference: http://buphy.bu.edu/~duffy/PY105/35b.GIF
this graph shows graph of two waves equal in magnitude but not identical, which pretty much cancels each other out when they meet a-b

Answer 4

Thanks so much :) I was struggling without seeing any graphs

Answer 5

Also can I ask one more quick question? When looking at what wave has the highest energy in the spectrum it would be a red wave right? or dark red
