Microscopes use lenses that are responsible to attain the … WebA periscope is a useful example of the law of reflection at work. It's important that your mirrors are placed at a 45° angle because light always reflects away from a mirror at the same angle that it hits it. In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle. Important Points

Class 10 Physics: Light Reflection and Refraction Notes

WebIn physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.
