(a) Polished wooden table - regular reflection

☃️ A polished surface is an example of asmooth surface .

☕ A polished wooden table has 9- smooth surface .

⭐ Hence, reflections from the polished table will be regular .

(b) Chalk powder - Diffused reflection

☃️ Chalk power spread on a surfaceIsan exampleof an irregular surface. It is not smooth .

☕ Therefore, diffused reflection will take place from chalk powder .

(c) Cardboard surface - Diffused reflection

☃️ Cardboard surface is also an example of an irregular surface .

☕ Hence,diffused reflection will take place from a cardboard surface .

(d) Marble floor with water spread over it - Regular reflection

☃️ Marble floor withwaterspreadoveritisan example of a regularsurface .

☕ This is because water makes the marble surface smooth .

⭐ Hence, regular reflection will take place from this surface .

(e) Mirror - Regular reflection

☃️ Mirror hasa smoothsurface .

☕ Therefore, it will give a regular reflection .

(f) Piece of paper - Diffused reflection

☃️ Although a piece of paper may look smooth, but it has many irregularities on its surface .

☕ Due to this reason, it will give a diffused reflection .

Answer 2

Question given:

To mention each case whether regular and diffused reflection will took place whenever a beam of light strikes.

Also Justify the answer.

Answer:

★Polished wooden table

↣Regular Reflection

The polished surface is an example of snooth surface. And a given polished wooden table has a smooth surface.

Thus, reflection from the polished table will be regular.

_________________________

★Chalk Powder

↣Diffused Reflection

Whenever chalk powder gets spreaded on a surface it becomes a example of an irregular surface. It is not smooth. Hence, the diffuse reflection takes place from chalk powder.

_________________________

★Cardboard Surface

↣Diffused Reflection

Cardboard surface is an example of an irregular surface, hence diffused reflection will take place from a cardboard surface.

_________________________

★Marble floor with water spread over it

↣Regular Reflection

In the case ,in which marble floor is spread over water ,it will become an example of a regular surface.It happens because water mixed with marble makes it smooth in surface.Thus, regular reflection will take place.

_________________________

★Mirror

↣Regular Reflection

We all know that mirror has a smooth surface therefore it will give our regular reflection when beam of light is striked.

_________________________

★Piece of paper

↣Diffused reflection

Inspite, a piece of paper is experienced smooth but it has many irregularities on the surface due to this vary reason it will produce a diffused reflection.
