Includes applications to sound (speed using echo timing and hearing limits via ear mechanics), refraction and absorption in glass, ultrasound imaging and wave reflection at material boundaries, and seismic wave behavior (P/S waves and refraction). Continues into electromagnetic waves, spectrum identification, TV remote and satellite links, and infrared energy transfer.","A Waves in air, fluids and solids  \n1.

Not all the light that enters the block leaves the block. What has happened to this light that does not leave the block? (1)  \nIt has been absorbed by the glass  \n7. (physics only) Sound waves in the air are converted into vibrations in solids within the ear (HT).  \na. Describe how the ear changes air vibrations into solid vibrations. (3)  \nCompressions in the air caused by sound (1) make the flexible eardrum vibrate (1)  \nSolid bones are connected to the eardrum which also vibrate as the eardrum vibrates (1)  \nb. Explain why this process limits the frequency range humans can hear. (3)  \nThe eardrum and solid bones can only vibrate at specific frequencies (1)  \nFaster or slower vibrations in the air do not produce vibrations in the bones (1)  \nThis limits the frequency of sound that can be heard (1)  \n8. The diagram below shows ultrasound being used to produce an image of the inside the body.  \nscreen  \na. Complete the following sentences. Choose from the correct words from the list below. (4)  \nmedia radiated transmitted reflected boundary  \nUltrasound can travel through different materials – solids, liquids and gases. When  \nultrasound meets a boundary between two different  \nmedia some of the ultrasound is reflected/transmitted and some is  \ntransmitted/reflected . The reflected pulses are seen on the screen.  \nb. Draw a trace on the screen to show how the ultrasound image will appear.
