Question

derive an equation for refraction of light for plane surfaces​

Answer 1

Explanation:

• This is vertical plane which is normal to the plane of the mirror.Again DAON = !
• angle of incident and DBON=r, the angle of reflection .Then i= r as shown in the when a beam of light incident on sooth surface, The reflection beam has the same angle of reflection which is called reflection

Answer 2

Answer:

n2/v-n1/u=(n2-n1)/R.
