Maddy, carole, and maria are enjoying a day at the beach. they are body surfing and playing on their boards. imagine that wave a catches up with wave b. describe the change, if any, in wave amplitude. a) there will be no change in either wave. b) wave a will cancel out wave b and amplitude will be 0. c) a new wave with larger amplitude than a or b will be the result. d) a new wave with smaller amplitude than a or b will be the result.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
