About This Quiz

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection.
Here are some questions explaining light reflection in detail, all the best for the upcoming quiz!

    The scattering of light off a rough surface is called...

    • Specular reflection

    • Diffuse reflection

    • Specular refraction

    • Diffuse refraction

    Correct Answer
    A. Diffuse reflection
    Explanation
    Diffuse reflection refers to the scattering of light off a rough surface. Unlike specular reflection, which occurs when light reflects off a smooth surface and maintains its original direction, diffuse reflection causes light to scatter in multiple directions due to the irregularities on the surface. This phenomenon is commonly observed when light bounces off surfaces such as paper, fabric, or walls, creating a softer and less focused reflection.

    In the figure above, the angle of incidence is  What is the angle of  reflection? - ProProfs

    In the figure above, the angle of incidence is  What is the angle of  reflection?

    • 1

    • 2

    • 3

    • 4

    • 5

    Correct Answer
    A. 3
    Explanation
    The angle of reflection is the same as the angle of incidence. In this case, since the angle of incidence is 3, the angle of reflection is also 3.

  • 4. 

    When light strikes a smooth and polished surface, what type of reflection occurs?

    • Diffuse reflection

    • Regular reflection 

    • Absorption 

    • Refraction

    Correct Answer
    A. Regular reflection 
    Explanation
    Regular reflection takes place when light strikes a smooth and polished surface, such as a mirror or a glass window. In this case, the light reflects at equal angles, producing a clear and sharp reflection.

        The diagram shows a single ray of light being directed at a plane mirror. What are the angles of incidence and reflection?   - ProProfs

        The diagram shows a single ray of light being directed at a plane mirror. What are the angles of incidence and reflection?  

    Correct Answer
    A.
    Explanation
    In the case of a plane mirror, the angle of incidence is equal to the angle of reflection. This means if a single ray of light is directed at a plane mirror with an angle of incidence of 40 degrees, then the angle of reflection will also be 40 degrees.
