Question #144844

Let’s consider the below geometrical layout.

1- Demonstrate that in arbitrary point “M”, the radius (r) has the expression

1- Demonstrate that in arbitrary point “M”, the radius (r) has the expression

Expert's answer

As per the information given we can say that

here M is the arbitrary point

Since figure is missing so we can assume that focal length is F for the reflector used

Now expression for r can be given as follows

Let us assume that angle between reflector and reciever be "\\phi"

So,

"r=\\frac{2F}{1+cos \\phi}"
