in the image above, an incident ray XY makes an angle of 15\( ^{\circ} \) with a fixed line AY, which is normal to surface of a plane mirror if the mirror is turned as indicated by the arrow through \( 40^{\circ} \), what angle will the reflected ray make with AY
a
\( 25^{\circ} \)
b
\( 40^{\circ} \)
c
\( 15^{\circ} \)
d
\( 55^{\circ} \)
e
\( 95^{\circ} \)

Angle of reflection when reflected is 2@
:. R= (15x2) + (2x40)
R = 30 + 80
R = 110 degree
Recall, R=2@
@=R/2, where @= the angle between Reflected Ray and AY
@ = 110/2
:.@= 55degree
D is correct
😁💛😁
