True or false the refraction of a wave is how many wavelengths pass a fixed point each second

False

Explanation:

- Refraction is the phenomenon that occurs when a light wave crosses the interface between two different mediums. Because of the different index of refraction of the two mediums (also called optical density), the speed of light in the two mediums is different, so the light changes direction.

- The definition described in the text of this problem, instead, is the definition of frequency. In fact, frequency of a wave is defined as the number of complete cycles (or of complete wavelengths) that pass a fixed point each second.

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.
