Solve this:

**Q.** While verifying the laws of reflection of sound, measured the angle between the incident sound waves and reflected waves as $54\xb0$. Calculate the angle of reflection .

let angle of incidence be x,

angle of incidence = angle of reflection

therefore,angle of reflection = x

given that,

angle of incidence + angle of reflection=54

x+x=54

2x=54

x=54/2

x=27

Therefore angle of incidence = angle of reflection = 27
