If a parabolic reflector is 20 cm in diameter and 5 cm deep, then the distance from vertex to focus is

Answer» ONG>Answer:

LET equation parabola y

=4ax

Oc=5 cm

So, x−Cordinate of point A=5

Ab=20

AC=

×AB=10

A(5,10)

A Lie on the parabola it will satisfting the eqquation y

=4×9×5

9=5

focus =(0,10)

=(5,0)
