INTRODUCTORY PHYSICS II (PHY 1020)
Prince George's Community College
PHY 1020 will be delivered as an on-line course beginning January 20, 2021. We will have video lectures via Blackboard
starting at 6:00pm on Monday and Wednesday evenings. To join the meeting, log in to Blackboard and look under "Course Content"
to find the link to the virtual classroom.
- For Lab Experiment #12 (final lab): Build the crystal radio from the kit provided at the beginning of the semester.
Instructions are provided with the kit. Connect an antenna and ground as described, and see if you can hear any radio stations.
If you can't hear anything during the day, then try again at night. If you can't hear anything at night, then try again during the day.
Remember that many radio stations reduce power or go off the air during the night, but you can hear more distant stations at night.
When you're done, take a picture of your finished creation and send it to me by email. Also let me know what you heard.
Could you hear anything? Was it daytime or nighttime? If the station identified itself, let me know the call sign.
You may keep your crystal radio after the course is over. It will run forever without needing batteries.
This lab is due Wednesday, April 28, 2021 (11:59 pm).
