What happens when the two waves meet? A.
They superimpose and remain at the same amplitude.
B.
They experience destructive interference and cancel each other out.
C.
They experience constructive interference and have twice the amplitude.
D.
They superimpose and have half of their original amplitude.

when two or more waves meet, they interact with other. The intersection of waves with other waves is called wave interference. wave interference may occur when two waves that are traveling I opposite directions meet. the two waves pass through each other, and this affects their amplitude

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.
