Refraction of Light
This physics video tutorial provides a basic introduction into the refraction of light. It discusses the law of reflection and the law of refraction which is also known as Snell's Law. The law of reflection states that the angle of incidence equals the angle of reflection. This video also explains how to calculate the angle of refraction as ...

Photoelectric Sensor Wiring Through-Beam sensors have two separate devices: - The emitter - The receiver The emitter is what sends the light out and the receiver is what catches the light. Both of these sensor devices will need to be connected to 24-volt DC power. The receiver will also be connected to the 24-volt DC “Motor Starter” coil. Watch the video and type down the correct answer in the comments below: The photoelectric sensor Brown wire is always connected to: a) The load b) 24VDC Return
