Question

state laws of reflection and refraction ​

Answer 1

There are three laws which govern Reflection and Refraction. These can be very easily derived from geometry.They are: Angle of Incident Ray with Normal(i) EQUALS Reflected Ray with Normal(r).(i=r) Popularly known as SNELL'S LAW it is n1*sin i=n2*sin e where i is same as above,e is angle of refracted beam with normal.

please mark as brainliest

Answer 2

1st law of reflection:-

according to the first law of reflection of light the incident ray the reflected ray and the normal at the point of incidence all lie in the same plane .

2nd law of reflection:-

according to the second law of reflection of light the angle of reflection is always equal to the angle of incident.

1st law of refraction of light:-

the normal incident ray and reflected ray lie at same plane

2nd law of refraction of light:-

sin I/sin R equals to constant

the ratio of Sin of angle of incident with the Sin of angle of refraction is constant .

Here is your answer
