What is the most insolation striking a smooth light colored solid surface?
reflected.
Why does rubbing of a matchstick on a rough surface lights up?
The rough surface causes a lot of friction when the matchstick rubs against it. Friction causes heat (try this for yourself by rubbing the palms of your hands together- they feel hot. Then consider how smooth our skin is in comparison to the rough surface, so you appreciate how much heat it generated.) The heat causes the wood of the matchstick to set alight. Actually, the head of the matchstick is coated in a more flammable substance (phosphorus), which makes lighting even easier.
Why it is difficult to walk on a smooth and polish surface?
Friction is needed for stability in movement.
Why is it difficult to walk on smooth and loose surface?
it is because smooth surfaces have less friction so when friction is less it is hard to walk
Is the force is greater on a smooth surface or on a rough surface?
smooth surface.

What will be the effect of incident ray of light striking a rough surface compared to the same rays striking a smooth surface?
If the surface is completely reflective then the angle at which the incident light leaves the surface will be different. For a rough surface the light would be scattered, whereas for a smooth surface they would reflect at the same angle the hit. If the surface isn't completely reflective then the angle and speed and which the light enters the object. For a rough surface the angles will random and based on the refractive index of the material. For a smooth surface they will be proportional to the sin of the angle times the refractive index.
Why it is difficult to walk on a smooth and polish surface?
Friction is needed for stability in movement.
Why is it difficult to walk on a smooth or rocky surface?
A surface that is too smooth can have insufficient friction for your feet to gain traction. A rocky surface, on the other hand, can be hard to navigate because of the uneven terrain.
Why is it difficult to strike a match on a smooth surface?
Heat necessary to lit a match comes from friction between match head and the surface. Smooth surface gives way less friction.
Why is it difficult to walk on smooth and loose surface?

Is the force is greater on a smooth surface or on a rough surface?
smooth surface.
Does a basketball roll faster on a smooth surface or a rough surface?
on a smooth surface
What type of surface weathers faster smooth surface or jagged surface?
jagged
What do snails prefer rough or smooth surface?
Smooth surface
Why is it difficult to view an oak leaf under a microscope?
An optical microscope focuses best on an object having a smooth flat surface. An oak leaf is difficult to focus on when viewed under a microscope because it has an irregular surface.
