Question

-Constructive and destructive interference can occur with either
transverse or longitudinal waves. T or F

-The variables known as "frequency" and "wave speed" are the same
except when describing longitudinal waves. T or F

-A helium-filled balloon, with a metal weight attached to its
bottom, is sinking to the bottom of a liquid-filled container. As
it descends, it will be acted upon by a continuously decreasing
buoyant force. T or F

Answer #1

1)**True(T)**

Constructive and destructive interference occur in both transverse and longitudinal waves.

2)**false(F)**

The wave and frequency are different physical quantities which are related by the formula:

Wave speed=frequency*wavelwngth

3)**false(F)**

From the formula of buoyant force qe know that this buoyant force is directly proportional to the volume immersed of sinking body in the liquid. As the baloon descends,the volume immersed in liquid gets increased resulting increase in the buoyant force.
