1.	(a) In the above activity, what will happen if you lift one of the tubes to some height?(b) Measure the angle of incidence 01 and the angle of reflection 02. Try to see if they are related in any way.
Answer» (a) If one of the tubes is lifted, angle of incidence will not be equal to angle of reflection, hence, the sound will not be clearly audible. (b) Angle of incidence is same as the angle of reflection.
