Charina says that when waves interact with an object, they will interfere with the object, and when waves interact with other waves, they will reflect off each other. do you agree with her? why or why not?

I completely don't agree with her, as a result of interference happens once waves act with alternative waves. Reflection happens once waves act with an associated object and bounce off it.

Explanation:

No, she has it backward. Waves interfere with one another and mirror off objects. once 2 waves overlap their amplitudes add. If they need a similar sign this addition is constructive, which means the amplitudes grow. If they need opposite signs this constitutes subtraction and also the waves will partly, or utterly cancel. this can be referred to as interference.

Reflection happens once waves travel from one medium to a different. If the wave electric resistance of the new medium is totally different (which it usually is) there'll be a partial, or maybe total, reflection.

I would not agree with her since reflection and refraction happens only when waves hit an object. When, waves meet it is either it experiences constructive or destructive interference. Hope this answers the question. Have a nice day.
