Answer 1

Answer:

AnSwEr iS BeLoW

Explanation:

Well according to https://van.physics.

The headlamp's concave mirror is open on one end, and the light bulb's filament is placed at or near the focus. Parallel ight rays, if they were coming into the headlamp from outside (say, the driver is driving his car in the direction of the setting sun), would converge near the filament of the light bulb

Hopes this helps :)

Answer 2
