I'm guessing you mean a microwave oven. There's often a bit of splatter when heating food, and slick surfaces are easier to clean. Apart from that, no reason. They would work just as well matte or drab.
because the light bounces off the flat and shiny surfaces.
a shiny surface so much light so brightly that it seans to glow
I believe that shiny surfaces reflect radiant energy.
If you are talking in terms of the suns heat being absorbed by the surfaces then I have the answer. Shiny surfaces naturally deflect the suns rays where as dark surfaces are easy conductors of heat as they naturally catch the suns rays. You will notice with leather or print on a shirt that it gets hot because the rays have nowhere to go. A shiny surface will just deflect it back.

Generally the fresh surfaces of metals are shiny.
Because, shiny surfaces reflect heat, they don't emit much heat and they don't absorb much heat!
the inner planets have rocky surfaces

They shouldn't. ;)

yes
The inner planets' surface materials differ from the outer planets because the inner planets have rocky surfaces and the outer planets have gas surfaces.
Yes.Even if it looks shiny, there's always some friction.
