A ray of light coming from the point (1, 2) is reflected at a point A on the x-axis and then passes through the point (5, 3). The coordinates of the point A are-
A
B
C
(–7, 0)
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
A
Let, the coordinates of point A is ( α , 0)
Now –m AB = m AR
If AR makes an angle θ with +ve x-axis, then AB makes ( π – θ ), therefore
–m AB = m AR
– 
= 
⇒ 2( α – 5) = –3( α –1)
⇒ α = 
∴ A is
