Question

Light incident on a Surface at an angle of 45° undergoes diffused reflection. At what angle will it reflect?

Answer 1

Answer:

0 degree to 180 degree

Explanation:

When a ray of light falls on a smooth and polished surface, then after striking it bounce back into the same medium, it is called reflection.

There are two types of reflection.

1. Regular or specular reflection: When some parallel rays incident on the smooth surface then after reelection, the reflected rays are also parallel to to each other, it is called regular reflection. In case of mirrors, the regular reflection takes place.

2. Diffused reflection: When some parallel rays falls on rough and unpolished surface, then after reflection, they are not parallel to each other.

The angle of incidence is 45 degree, in case of diffused reflection , the angle of reflection is some where between 0 degree and 180 degree.

Answer 2

The angle(s) that it will reflect will be at any angle between -90° and 90. The correct answer between all the choices given is the fourth choice or letter D. Lmk if this is correct
