The answer is - both magnetic poles</span>
<span>In the earth's southern magnetic pole, auroras are known as aurora austalis or southern lights while in the northern magnetic pole they are known as aurora borealis or northern lights.</span>
<span>They are caused by charged particles borne in solar winds that are escaping from the sun. As they approach the earth, the winds distort the earth's magnetic field which allows some particles to enter the earth's atmosphere, where they excite the gases and make them glow with spectacular display of colors.</span>

the reflected light ray is 35° to the normal.
Explanation:
the light ray hitting the reflected surface is the incident ray, and forms an angle of incidence with the normal (the line perpendicular to the reflecting surface). The ray reflected fron the surface is called the reflected ray, and forms an angle of reflection.
since
the angle of incidence=angle of reflection
35° = 35°
