help with light waves and sound waves

Question

 

 

 

1,  do sound waves reflect off an object, then angle of  incidence equals the angle of reflection

2.  do light waves reflect off an object, then angle of incidence equals the angle of reflection

 

 

3.  when there is destructive interference occurs when waves are out of place, is the sound waves?

4.  when there is destructive interference occurs when waves are out of place, is the light waves?

 

thanks

Answer 1

1) yes

 

2) yes

 

3) yes

 

4) yes

 

Light waves and Sound waves can be described using the same wave equations because they both have forms of waves. The sounds move through the air by pressure difference (it's like a slinky contracting and expanding as it moves), but the way sound moves throughout the medium is described in equations used to describe waves.
