1.0What Will Students Learn in Chapter 11: Light?
- Students will understand how light reflects off surfaces, the laws of reflection, and the roles of the incident and reflected rays, along with the angles of incidence and reflection.
- They will explore concave and convex mirrors, learning how these mirrors form different types of images (real and virtual) depending on the object's position.
- Students will study convex and concave lenses, understanding how these lenses bend light to form images, and learn about focal length and image formation through lenses.
- The chapter provides insights into the structure of the human eye, its working, and common vision problems like nearsightedness and farsightedness, along with their correction using lenses.
- Students will discover that sunlight consists of various colors, which can be separated to form a spectrum, demonstrating the concept of white light and its components.

Frequently Asked Questions
A concave mirror is a mirror that curves inward and can form both real and virtual images. A convex mirror curves outward and always forms virtual images that appear smaller than the object.
The human eye works like a camera, where light enters through the pupil, is focused by the eye lens onto the retina, and the image is sent to the brain for interpretation.
A real image can be projected on a screen and is formed when light rays converge. A virtual image cannot be projected and is formed when light rays appear to diverge from a point.
