Answer 1

Regular reflection

The image of a mountain can be clearly seen in a calm water of lake. This is regular reflection.

All other objects like buildings, trees, etc can also be viewed clearly on lake when the water is calm.

Explanation:

Regular reflection:

• Regular reflection is also known as Smooth reflection.
• It occurs on surfaces like Clear water, Mirrors, etc.
• It is said as regular reflection because it reflects back most of the light that falls on it.

Irregular reflection:

• Irregular reflection is commonly known as Diffused Reflection.
• It occurs on surfaces like wood sand and all other rough surfaces.
• It is said as irregular reflection because it absorbs most of the light that falls on it and emits only few rays of light.
