Lexy and jin study the diagram shown.
which best explains who is correct?
2=
2
> n=1
lexy is correct because angle r is between the incident
wave, n = 0, and a diffracted wave.
© lexy is correct because angle r includes the diffracted
wave at n= 1.
jin is correct because angle s is measured from the
barrier and includes n = 2, the wave that has the most
diffraction.
jin is correct because angle s is between the dimmest
order bands, n= 1 and n = 2.

lexy says that the diffraction angle is the one labeled r, and
jin says that the diffraction angle is the one labeled s.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
