Question

I wasn’t able to find the formula and correct way to do these could someone help me with these?

utrasonic dagnosties may be used to locate a tumor in an organ such as the lives. The figure shows a beam of utrasonic waves that enter the sureunding medum, refract into the Ives, reflect off the tuamo, and retract nto the anordng med m. If the?eed of the wave asttraveb twough the her 2.5% kus than when it in traveling through the surounding medium, determine the depth of the tumor it Liver beam of ight enters a nt gs u dk with an dex of reaction of 1.600 at the mpoint of the at ude as shown in the re Detomne the angle of cisance in ar such that the reftacted light w
