Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who invented Charge-coupled device?1969
2. What is the inventors?Willard Boyle and George Smith
3. What is the primary application?Digital image sensing
4. What is a charge-coupled device (CCD)?A CCD is a tiny silicon chip that turns light into electrical charges, which are then moved and read out to create a digital picture.
5. How does a CCD capture light to make a picture?When light hits the silicon, it frees electrons that are collected in tiny wells. The device then shifts these charges across the chip so each pixel can be measured.

Charge-Coupled Device (CCD): A semiconductor device that converts incident light into an electrical signal for digital imaging.
Photoelectric Effect: The emission of electrons from a material when light shines on it.
Potential Well: A region on a semiconductor chip where electrical charges can be stored.
Charge Transfer: The controlled movement of electrical charges from one location to another within a semiconductor device.
