A ray of sound has an incident wave that has a 30 degrees incident angle when it hits a mirror. What is the angle that is made with the mirror and the reflecting wave?Concept Check A ray of sound has an incident wave that has a 30 degrees incident angle when it hits a mirror. What is the angle that is made with the mirror and the reflecting wave? square Lesson 4.6 - Reflection14. A wall cavity with a reflective surface has a higher R -value than just the cavity Explain why this occurs. __Unpolarized light with an intensity of 100W/m^2 passes through a polarizing filter completely vertical. It then passes through a second polarizing filter (an analyzer) with an angle of 30 degrees, relative to the first one. What is the intensity of the light (in Watts per meter squared as it passes through the second filter? Do NOT round, and do NOT include a unit in your answer.8. Tungsten , a poor conductor, is used as a filament in some lig!
