When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 117 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far (in terms of...

A ray of light traveling in air strikes a boundary at an angle of 57.3 degrees to the normal. After crossing the boundary, the ray travels at an angle of 34.8 degrees to the normal. What is the speed of light in meters per second in the second medium? (The answer should be given in scientific notation with two digits right of the decimal; for example, 1.23e+5 means 1.23 times 10 to the 5th power.)

3. Earthquake warning system A typical earthquake produces two types of seismic waves. P ("primary" seismic waves are longitudinal waves that move through the earth's upper crust with speed anywhere from 3 km/s to 5 km/s (the exact speed depends on the local composition of the earth's crust). S ("secondary") waves are transverse waves that move slower than P waves. The S-wave speed is typically about 60% less than the P-wave speed in any given material. The map below shows...
