power output per unit area and is measured in watts per square meter W / M squared a sound wave intensity can be calculated using the above equation for a stance of the Waves amplitude in meters and an S stands for the frequency of vibration in hertz.

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
