The ball skewed off at a right angle.

球呈直角偏离弹了出去。

The key was bending the light the optimal amount, enough that it enters the solar panel at an angle, but not so much of an angle that the light reflects off and is lost.

这其中关键在于折射最理想数目的光线，也就是让尽量多的光线转到能进入太阳能板的入射角度，而使尽量少的光线处于被反射掉的入射角度。

The amount of specular light that reaches the viewer depends on the location of the viewer and the angle of the light bouncing off the object.

射向观察者的反射光数量依赖于观察者所处的方位以及对象上反射光的角度。

“Most aerodynamic things take off at very gradual angles, but this has a very striking, very powerful lift angle, ” Swartzlander says.

Swartzlander says：“大多数空气动力装置起飞的角度很平缓；而这样的装置起飞时角度变化非常剧烈，非常惊人。”

For example, insects can see polarised light - light to them appears as different colours, depending on the Angle at which reflects off different surfaces.

例如，昆虫能够看到极光——光对它们来讲会根据从不同的表面反射的不同角度而显现出不同的颜色。
