Answer 1

Answer:

Convex mirror is a part of spherical mirror having its outer bulging surfaceas reflecting surface.

Answer 2

Answer:

yes

Explanation:

because the aspherical logic based behind refracting troubulous light waves is incongruously fracturing at any give time. This proves that an arrangement of refracting monotonous light is correct.
