Lab Report

Introduction:
The main purpose of this lab was to go far a hands-on experience of lead and their properties. A crystal rectifier is a semiconductor that allows electric current to flow exactly in one direction and blocks electricity in the arctic direction. LED meaning perch Emitting crystal rectifiers is a type of semiconductor diode that is forward biased or pushes electrons to a lower energy. In this lab, we observe the properties of LEDs using a 9V battery.




Procedure
1.Exploring the LED Color Strip
?We committed the LED Color Strip to the battery. We touch the LED combusts and we tangle no heat come from them. Next, we connected the incandescent myeline and after 5 seconds it began to generate heat.
?Next, we needed to look at the LED in a hostile control, but receivable to the fact that the project didnt come with a remote control and a Infrared Radiation Detector we could non complete steps 3 through 6.
1.Observing Diode Behavior
? jump, we connected the LED Color Strip and all of the lights came on except for the last light on the end (which is the IR LED ). Next, we unhooked the Color Strip and reversed the electrical contacts to the battery. The LEDs did non come on.
?Then, we touched the leads of the small incandescent lightbulb to the validating and negative terminals of the battery; the bulb came on.



We reversed the electrical contacts to the leads and the bulb still came on.
1.Determining the Relative Wavelengths of Light
?One of group members, rest approximately 1 meter away from the some other partner, positioned the LED Color Strip vertically while it was connected to the battery. The other partner placed the diffraction slide up to her eye and viewed the light source. We then drew out what the diffraction grating looked like.
1.Determining the Wavelengths of Light Quantitatively
2.Determining the Relative Energies of Colors Using a Capacitor
?First we connected the LED Color Strip to the battery. Next we mixed-up the Color Strip from the battery and...If you want to get a full essay, order it on our website: Orderessay
