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. What is the core principle?Real-time correction of optical wavefront distortions
2. What is the primary application domains?Astronomy, ophthalmology, microscopy, and laser communications
3. What is adaptive optics and how does it help telescopes?Adaptive optics is a technology that fixes blurry pictures caused by the Earth's atmosphere. It uses sensors and a special mirror that changes shape to cancel out the distortions, making stars and planets look sharp.
4. Why do stars twinkle and how does adaptive optics stop the twinkle?Stars twinkle because the air between Earth and the stars changes temperature and pressure, bending the light. Adaptive optics measures those bends and corrects them quickly, so the stars appear steady.

Wavefront Aberration: Deviations of a light wave's shape from an ideal, planar or spherical form.
Deformable Mirror (DM): A mirror whose surface shape can be actively controlled by actuators to correct optical errors.
Diffraction Limit: The theoretical maximum resolution of an optical instrument, determined by the wavelength of light and the aperture size.
