And what we find out is the wavelength of a Matsuzaka fastball is 1.1 times 10 to the -31 meters.

我们算出松阪快球的波长,是1，1乘以10的负31次方米。

For example, if we're talking about a pitcher, like Matsuzaka, we might want to know the speed of his average fastball.

举例来说，如果我们谈到一个投手，就像松阪，我们想知道他投出,快球的平均速度。

So, if we're trying to figure out the wavelength of a Matsuzaka fastball, we need to consider the velocity first, which is 42 miles per hour.

如果我们尝试计算一个,松阪发出快球的波长，我们首先需要考虑速度，每小时为42英里。

So, that's for Matsuzaka, and even if you don't memorize all the wavelengths for all the pitchers.

所以，那是对于松阪的情况，即使你没有记住,所有的投手投出球的波长。

And the example we'll pick is considering, for example, a Matsuzaka fastball.

我们举例来考虑的是，一个松阪的快球。

So, first we have Matsuzaka at 94 miles per hour.

所以，首先我们知道松阪的,投球速度是94公里每小时。
