What is Optics?

Optics – or the science of light – is the study of how light behaves and interacts with the world. In these days of COVID-19, optical technologies, from cameras and computers to fiber optic cables, are helping to keep us all connected. We know this also means many families are now working and learning at home. As we approach the International Day of Light on May 16, OSA is pleased to offer this webinar and other optical activities and experiments families can do at home together.

REGISTER NOW: Optics Magic with Judy & Nancy: REFLECTING ON LIGHT

What reflects light? Can you predict the path of reflected light? In this webinar, you will learn more about light and apply what you have learned about the behavior of light to make a rule. This webinar will include two activities you can do at home with materials you can find around your home. These activities are geared towards elementary and middle school students but are fun for kids of all ages.  

Activity 1: What reflects light?

Activity 2: Apply what you have learned to make a rule for reflection (Law of Reflection)

Materials: To fully participate, you’ll want to gather these materials before we begin. 

1. A flashlight

2. A CD jewel case lined with a piece of black colored paper. A small mirror will work too.

3. Five (or more!) objects from around your house to test

4. A laser pointer or a flashlight with a narrow beam 

5. A piece of paper with perpendicular lines drawn on that meet at the center.  If you have a protractor, you can use it.

Check out this parent and teachers guide to learn more about the activities Judy and Nancy will be demonstrating during the webinar.

Speakers

Judy Donnelly

Judy is retired from Three Rivers Community College where she was professor of physics and technology for 36 years and Program Coordinator for the Laser and Fiber Optic Technology associate degree program. She is a senior member and fellow of OSA and SPIE and has served on outreach and education committees of both societies as well as other national and international STEM education initiatives. Judy was awarded the Educator Award by SPIE (2003) and the OSA Esther Hoffman Beller Medal (2012) for outstanding contributions to education in optical science and engineering. Judy enjoys gardening, knitting, baking bread and answering the very difficult science questions asked by her three grandchildren. 

Nancy Magnani

Nancy started her career in engineering as a senior engineer designing and testing high speed fiber optic systems for a telephone operating company.  After relocating to Connecticut, Nancy transitioned to a career in education.  As a Science Specialist/Grant Facilitator for a regional education service center, Nancy provided science professional development to teachers and wrote and facilitated STEM grants programs for 4^th grade through high school students throughout eastern Connecticut.  Grant programs included energy, robotics and collaborating with Judy Donnelly on optics and photonics. Nancy currently is with the Sumner School district, Sumner, WA working with middle school science students, facilitates science club and judges STEM Fair projects at the school, district and state levels.  She is a member of National Science Teaching Association (NSTA) and a senior member of both OSA and SPIE.
