Question

which of the following is not correct for irregular reflection reflection(A) it cut off glare (B) it takes places from most of the surface (C) it help in general illumination (D) it help in the formation of virtual image​

Answer 1

The statement which is false for Irregular reflection:

✊It helps in the formation of Virtual Image

$\large{ \underline{ \boxed{ \bf{ \purple{Option \: ( \red{D})}}}}}$

Explanation:

• When rays of light incident on rough, unpolished and uneven surfaces which is full of irregularities, Irregular/Diffused reflection takes place.
• The light after being reflected back spreads in wide area, and helps in general illumination.
• The Non-luminous objects can be or visible only due to this kind of reflection.
• But, This type of reflection doesn't help in any kind of image formation, because the extended Ray's couldn't meet each other properly.

When light reaches any kind of surface, three phenomena of light rays can occur:

• Absorption
• Transmission
• Reflection

➤ Reflection is the bouncing back of light rays in the same medium. This occurs when the light rays hits on any surface. When a surface reflects most of the light, the surfaces are known as Reflecting surfaces.

• Polished silver mirror reflects light the most.
• Colour of any object depends upon the colour of light reflected by it. Rest colours are absorbed.
• The laws of reflection states that the incident ray, normal and reflected ray lies on the same plane. And, Angle of incidence = Angle of reflection.
• Direction of reflected rays depends upon the surface. Regular reflection occurs when the surface is polished and smooth.
• Irregular reflection occurs when light hits any uneven, irregular surface like wood, bark of tree etc.

Option(D)

Explanation:

When rays of light incident on rough, unpolished and uneven surfaces which is full of irregularities, Irregular/Diffused reflection takes place.

The light after being reflected back spreads in wide area, and helps in general illumination.

The Non-luminous objects can be or visible only due to this kind of reflection.

But, This type of reflection doesn't help in any kind of image formation, because the extended Ray's couldn't meet each other properly.
