what is prism plz plz plz plz plz plz plz help me today is my exam
Answers
Explanation:
prism is a wedge-shaped transparent body which causes incident light to be separated by color upon exiting. The separation by color occurs since different colors (corresponding to different wavelengths) of light travel at different speeds in a solid (although at the same speed, namely the speed of light, in a vacuum). As a result, refractioncauses the wavefronts of different wavelengths to be deflected different angular amounts. Since "white" light is really a superposition of different wavelengths, the prism therefore has the effect of angularly separating the incident light by color.
Answer:
prism is a diverging triangle .
it diverge the light in to several colours .
In the prism the angle of incident is equal the angle of reflection
