See width represent soze of beam yes that perpendicular to the Direction of travel. My question is when the deviation angle same why the width is variable

Its helpful. . One more question is that if we take single color then the angle of deviation is same but also width of beam after refraction changes mathematically how that is physically possible ?

The size of light beam is same or different before and after refraction from a medium. If same then why we can not prove from mathematical expression. If not same why?

Still my doubt is that out of these two which is correct. If anyone solution is wrong then why ? Out of this.

Like after reflecting concave mirror if the ray retrace its paththen also we can get a value of x that is also a probability.

How many posible answer of this problem

Is this solution is possible if not then why?
