Light Class 7 Science Notes – Chapter 15

White light consists of seven colors. The path in which light travels is a straight line. A smooth or shinning surface that forms images by reflection of light is called a mirror. Types of images formed with mirrors –

• Real image – Images that can be obtained on the screen are called real images. The image formation is in inverted form and occurs due to converging Lens.
• Virtual image – Images that cannot be obtained on the screen are called virtual images. The image formation is upright and occurs due to diverging Lens. Please refer Light Class 7 Notes for more revision notes.
