Laws of Reflection and Refraction 

There are three laws which oversee Reflection and Refraction. These can be handily gotten from geometry.They are: 

Point of Incident Ray with Normal(i) EQUALS Reflected Ray with Normal(r).(i=r) 

Prevalently known as SNELL'S LAW it is n1*sin i=n2*sin e where I is same as above,e is point of refracted shaft with ordinary. 

The INCIDENT ray,REFLECTED beam, REFRACTED beam and the NORMAL at the purpose of occurrence all lie in the equivalent plane.The plane is alluded as plane of frequency. 




The applet would produce an episode beam from the point you click in the UPPER LEFT REGION. The valuable subtleties that you will get are 

Edge of incidence(i) 

2.Angle of Reflection(r) 

3.Angle of Refraction(e). 

4.Critical Angle. 

5.A message TOTAL INTERNAL REFLECTION will be shown at whatever point something like this occurs. 


 All things considered, that is clear as crystal yet... 

Simply continue clicking in the upper left district 

You can increse or diminish either mediums refractive 

records by clicking INC or DEC 



 Well,i might here want to list the optical ideas that I have used in making this applet 

The above recorded laws 

Basic point It is the occurrence edge at which edge of refarction becomes 90 degree. 

All out Internal Reflection A wonder when light occurrence doesn't get refracted. The over two wonder requires light going from denser to rarer medium.
