wave interactions bench mark assessment. 1.which is an electro magnetic wave-light 2.which type of electromagnetic waves do most organisms emit-infrared waves 3.how does solar energy travel through earth-through convection 4.which wave can travel in both empty space and matter-radio 5.in which medium will a sound wave move more quickly-rock 6.A sound wave has a frequency of 20hz and a wavelength of 100m. what is the wave soeee-2000 m/s 7.Absortuon of a light wave occurs in what materials-all materials. 8.what happens to most of the light waves that strike a clear pane of glasd-transmission 9.which is an example of refraction-a sunbeam sticking a window 10.which describes how light waves can interact with wood-absorption and reflections. I got all the wrong after asking many people for answers, so I would like to try to guarantee that nobody else will get mislead, this is a 7th grade test.​
