• So there was a good question in Wednesday's class about the de Broglie wavelength and if it can actually go to infinity.

    在周三的课上有个关于德布罗意波波长的问题,非常好,就是它能不能到无穷大

  • So, a massless body cannot have a net force on it, because the acceleration of the rope cannot be infinite.

    所以没有质量的物体不会受到力,因为绳子的加速度不可能是无穷大

  • I would think that it would approach inifinity, and I would need to think about it and get back to you in terms of why we don't actually hit it and see something with an infinite wavelength.

    我会认为波长会接近无穷大,而且我需要考虑一下,然后返回来告诉你,为什么我们没有说对,为什么我们没有看到,无穷大波长的东西。

  • This is infinity. Let's call this 3, 2, 1.

    它是无穷大的,我们叫它3,2,1吧。

  • You cannot have a spring pulled only at one side, because then it will then accelerate with infinite acceleration in that direction.

    你不可能对弹簧只施加一边的拉力,因为那样的话弹簧就会以无穷大的加速度加速,就在这个方向上

  • STUDENT: Why doesn't wavelength go to infinity as it stops, like a standing .

    学生:当它停下来时,它的波长为什么,不趋于无穷大呢,就像一个。

  • Yeah. So, the force actually goes to infinity, and specifically it goes to negative infinity.

    是的,力变成无穷大,更具体说是负无穷大

  • Infinity is the force when we're thinking about it and our brains, negative infinity is when we actually plug it into the equation here, and the reason is the convention that the negative sign is just telling us the direction that the force is coming together instead of pushing apart.

    说力有多大时,我们想到的,是无穷大,而方程解出来的,是负无穷,这是因为习惯上,我们用负号表示力的方向,是相互吸引而不是相互排斥的,所以我们可以用库仑定律。
