Physics help!?

Last year I felt an earthquake while I was watching television. The earthquake that I experienced produced a wave that travelled through the earth at a speed of 1.3 X 10^4 m/s. This wave is incident on a boundary between two types of materials. If this incident angle is 35 and the refracted angle in the second... show more Last year I felt an earthquake while I was watching television. The earthquake
that I experienced
produced a wave that travelled through the earth at a speed of 1.3 X 10^4
m/s. This wave is incident on a
boundary between two types of materials. If this incident angle is 35
and the refracted
angle in
the second medium is 32 what is
the speed of the wave in the second medium
