    Question

    An optically plane surface reflects a beam of light –

    A as a parallel beam in one direction Correct Answer Incorrect Answer
    B as diffused beams in all d rections Correct Answer Incorrect Answer
    C as parallel beams in all direactions Correct Answer Incorrect Answer
    D as a diffused beam in one direction Correct Answer Incorrect Answer

    Solution

    An optically plane surface reflects a beam of light as a parallel beam in one direction. The set of incident rays are reflected as a set of rays. In other words, a beam of light is reflected as a beam of light if the mirror is plane and its reflecting surface is smooth. This type of reflection of a set of rays is called Specular Reflection.
