A ray of light moving parallel to the x-...

A ray of light moving parallel to the x-axis gets reflected from parabolic mirror whose equation is `(y-3)^(2)=8(x+2)`. After reflection, the ray must pass through

A

(0, 3)

B

(3, 0)

C

(0, 0)

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
We know that any ray parallel to the axis of a parabola after reflection passes through the focus of the parabola. The coordinates of the focus, are(0, 3). Hence, the ray passes through the point (0, 3).
