Which of the following statements about the reflection of light in a plane mirror is true?

medium MCQ 3 marks Class 6 · Science · Light, Shadows and Reflections
  1. A) Light always travels in straight lines.
  2. B) The angle of incidence is always equal to the angle of reflection.
  3. C) The angle of reflection is twice the angle of incidence.
  4. D) Light does not reflect in a plane mirror.
Answer
B) The angle of incidence is always equal to the angle of reflection.

The correct answer is B) The angle of incidence is always equal to the angle of reflection. — Therefore, option B is correct.

Step-by-step solution

  1. Recall that the law of reflection states that the angle of incidence equals the angle of reflection.
  2. Check each option: A) Only true for straight‑line propagation, not the definition of reflection. B) This is exactly the law of reflection. C) Incorrect; the angles are equal. D) Incorrect; mirrors always reflect.
  3. Therefore, option B is correct.
Common mistake: Confusing reflection with refraction

Concept tested: Law of reflection
