Question

Identify whether the following phenomenon are attributable to diffuse reflection (DR) or regular reflection (RR):
_RR__a. Water is sprayed onto a sheet of paper. A laser beam is directed towards the paper and reflects and produces a red dot on the ceiling.
It is a regular reflection because when we spray water on paper the surface of the paper becomes smooth.
___b. Light from the overhead lights strikes your body and reflects towards all your classmate's eyes.
___c. The image of a mountain can be clearly seen in the calm waters of a lake
___d. A lacquered table top produces a glare of the lamp bulb in the overhead light.

Answer 1

Answer:

Explain the differences between regular and irregular reflection light.

...

Solution.

Regular reflection of light Irregular reflection of light

This type of reflection occurs on smooth surfaces such as a plane mirror. This type of reflection occurs on rough surfaces such as a blackboard

Answer 2

1. Regular reflection
2. Diffused reflection
3. Regular reflection
4. Diffused reflection

• In case of a Diffused reflection the incident rays get reflected in all the directions.
• While in case of a regular reflection the incident rays get reflected back in a particular direction.
• Diffused reflection is caused by the surfaces that are not smooth while regular reflection occurs from smooth surfaces.
• Hence the cases where the surface is not smooth, their answer would be Diffused reflection while for others it will be regular reflection.
