Light Reflection And Refraction Science Quiz For 10th Grade

Let’s start the quiz

Light is a form of energy and it always travels in the straight line that forms a shadow. When light travels from one medium to another medium, it does three things- some of it bounces off, some of it goes through, and the rest of it is absorbed. So in this quiz, we focused on two things first one when light bounces and it is called reflection and another one is light goes through the medium and it is called refraction. So take this interesting quiz and know more about light reflection and refraction.
