DEFINE reflection and refraction of light. give its law and condition
Answers
Answer:
Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection can be used to understand the images produced by plane and curved mirrors.
The law of reflection states that the incident angle and reflection angle are equal to each other. While the law of refraction states that the ratio of the sine of an incident angle to the sine of the refraction angle is a constant value. Reflection generally takes place in mirrors.
Refraction is the bending of the light rays. For example a prism, a straw in a cup of water , and lens , all the example shows refraction of the light rays. in different angles. For example when you put a straw in a cup of water it refracts light
